Tons of DIY Monster Birthday Party Decorations & Activity Ideas!

I love to DIY. I hoard crafting supplies and pin new ideas like it’s my job. However, I rarely get much crafting done beyond the planning part. This party was quite the exception. Thanks to launching my new monster birthday shirt collection in August I’ve been doing monster-themed crafts for this blog (and saving them for Aidan’s birthday party) for months. Turns out months is what I need to actually be prepared for a party.

We decided on a chicken (nuggets) and waffles brunch theme to keep the food simple. Plus, Aidan had been waking up from nap really cranky so an early party was guaranteed to be more fun for everyone. We catered chicken nuggets from our local favorite, PDQ, and pre-made Belgian waffles from scratch. We baked them the day before the party and froze them once they cooled down (after taste testing a few…). Then we simply heated them up in the oven for 3 minutes at 400 degrees during the party. They were perfect!

Aidan's monster birthday party was bright, fun, and stuffed full of awesome monster DIYs. Check out this giant list of easy-to-do monster birthday party decorations, kid-friendly activities, and adorable party favors.

Monster Birthday Party Decorations – Tips & Tutorials

Most of these decorations were pretty quick projects, but if you want to do a lot that time adds up. Start early or invite friends over for wine and a crafting night!

Monster wreath // Aidan's monster birthday party was bright, fun, and stuffed full of awesome monster DIYs. Check out this giant list of easy-to-do monster birthday party decorations, kid-friendly activities, and adorable party favors.1. Monster Birthday Wreath

I made this cute furry monster wreath in October for Halloween knowing I would reuse it for Aidan’s party. You can find the tutorial here. All I added for his birthday was a hat made out of a piece of felt and attached with a straight pin.

I like having a sign on the door so people who haven’t been to our house before know they’re in the right place. Plus, it’s the first taste of our party theme.

Monster footprints // Aidan's monster birthday party was bright, fun, and stuffed full of awesome monster DIYs. Check out this giant list of easy-to-do monster birthday party decorations, kid-friendly activities, and adorable party favors.2. Monster Footprints

These were so fun and simple! Big monster footprints to welcome other monsters to our party. If you want to create your own, here’s a free template for my monster foot. Just print, cut, and trace onto black cardstock. More detailed instructions are on this blog post. (I laminated mine so I can reuse them in the future, because I’m a crafting packrat who is obsessed with her laminator. It’ll be fun to have for Halloween parties too!)

Monster pillows and pom poms // Aidan's monster birthday party was bright, fun, and stuffed full of awesome monster DIYs. Check out this giant list of easy-to-do monster birthday party decorations, kid-friendly activities, and adorable party favors.3. Pillow and Pom Pom Monsters

Aidan is obsessed with soft fabrics, especially fur and pom poms. He likes to tickle his nose on them. Months ago I found HanniLou Crafts on Instagram and loved her furry couch monsters. I bought the lime green one in the photo from her super early. When I found this teal fur at the craft store I thought companion throw pillows would be a really fun detail that Aidan would love (and again, something I could save for Halloween!)

For the pom poms I was originally thinking of creating a simple pom garland until I saw this post on Lia Griffith’s blog and loved the idea of adding monster faces on them. I didn’t use her template for the faces because I didn’t want to cut out more paper. I just freehand cut eyes, mouths, and tongues from felt scraps. I scattered about ten of these around tables and the mantle, then hung a few from light fixtures in the main party room and bathroom (and I sadly didn’t get any pictures of them hanging up but they were cute, promise).

Happy Birthday Banner // Aidan's monster birthday party was bright, fun, and stuffed full of awesome monster DIYs. Check out this giant list of easy-to-do monster birthday party decorations, kid-friendly activities, and adorable party favors.4. Happy Birthday Balloon Sign

I shared the tutorial and free template for this happy birthday banner DIY a couple months ago. It’s really easy and a fun, unique banner! I put this one above our entryway table and left it up until his actual birthday later in the week. (I had wanted to make extra balloons for his name but left that for the day before the party so of course ran out of time.)

Party At Your Door custom monster decor // Aidan's monster birthday party was bright, fun, and stuffed full of awesome monster DIYs. Check out this giant list of easy-to-do monster birthday party decorations, kid-friendly activities, and adorable party favors.5. Party At Your Door Monster Decor

The power crafting duo behind Party At Your Door saved me on Aidan’s first and second birthdays. (Those years when I wanted to DIY and then didn’t actually get anything done.) This year they made a whole monster birthday kit for me when I was launching Yippitee. They are geniuses with paper and hot glue and have really fun garland, banners, centerpieces, cupcake toppers, confetti (which you can personalize with your kiddo’s name and age!), and really any custom party decorations you need on their site. I put their banner behind our cake table and arranged their centerpieces and confetti around the table. It was a great backdrop for pictures of the birthday boy! (By the way, I used these Scotch reusable sticky dots to hang it up and am obsessed. They’ve been a go-to of mine since putting up Halloween decor. If they get paper residue on them you can just wash it off with soap and water!)

Googly eye cups // Aidan's monster birthday party was bright, fun, and stuffed full of awesome monster DIYs. Check out this giant list of easy-to-do monster birthday party decorations, kid-friendly activities, and adorable party favors.6. Googly Eye Cups

This is a MUST do for any monster party – it’s so easy and makes such a fun impression! I didn’t even glue eyes to all my cups – just a handful of each color that I had displayed near the drink dispenser. I bought these bright colored cups and hot glued on different sized googly eyes I found at my local craft store. The hot glue was great because I was able to pop the eyes off later on any cups that weren’t used so I could keep them for the next party.

Monster Utensil Holder // Aidan's monster birthday party - tons of easy DIY decoration, kid-friendly activities, and adorable party favor ideas to save. 7. Monster Tissue Box Utensil Holder

I saved empty tissue boxes during our annual Fall cold season, knowing I wanted to make some into monster faces. I used a square box for this and used rectangular ones for my monster bug toss game you can see under the Activities section. For the one in this picture, I cut out cardstock and taped it to each side. That meant no waiting for paint to dry but was a tad more work than I wanted. I ended up painting the rectangular boxes and next time would do that for all of them. You could also wrap it in wrapping paper or even colorful duck tape. But painting is probably the easiest. I wish I had made more just for fun decor all over the tables. Next time!

Monster cake // Aidan's monster birthday party was bright, fun, and stuffed full of awesome monster DIYs. Check out this giant list of easy-to-do monster birthday party decorations, kid-friendly activities, and adorable party favors.8. Monster Birthday Cake

I enjoy baking but I can’t decorate a baked good for the life of me so I like finding local bakers for Aidan’s party sweets. Mary Lee from Magnolia Lee Baking & Sugar Art is in a local Austin makers group with me so I see her gorgeous cakes all year long. I was so excited for her to make a monster cake this year for Aidan’s Yippitee birthday and she did NOT disappoint! How amazing is this cake?!! She used all of the finger puppets from my Yippitee birthday shirts and made it into a space-themed cake since the monsters are very alien-like. The bottom layer is the moon, with monster popping out of craters, while the top layer is outer space, with monsters in UFOs and space helmets. When chatting about monster decor ideas, I didn’t want to go the a scary route as Aidan is recently starting to be afraid of the dark and saying that things scare him. But he loves space and was so in love with this cake. You find find the finger puppets to make your own amazing space monsters cake here.

Monstrously Fun Toddler-Friendly Activities

Since Aidan is only 3 his parties are still largely for us adults so we wanted to have some games and activities to keep the kids busy while us parents could catch up and relax. Below are the games I organized, though we were lucky to have nice December weather and let them run around outside too.

Felt monster masks // Aidan's monster birthday party was bright, fun, and stuffed full of awesome monster DIYs. Check out this giant list of easy-to-do monster birthday party decorations, kid-friendly activities, and adorable party favors.1. Felt Monster Masks

I got addicted to making felt masks after I made Aidan’s first one in October. Since I knew Aidan’s birthday party was on the horizon, I made a few a day whenever I had the time. (Great for keeping your hands busy while on a Netflix binge!) The colorful masks greeted our guests at a small table in our entryway. I added a mirror to the table so the kids could easily see themselves too. These were an awesome party favor that helped everyone get in the monster spirit (and meant more fun pictures too)! Get the instructions and free pattern here.

Monster Party Hats // Aidan's monster birthday party - tons of easy DIY decoration, kid-friendly activities, and adorable party favor ideas to save.2. Decorate a Monster Hat

Aidan also loves party hats so I wanted to have some colorful monster hats. I was thinking of making this an activity with plain dot stickers and markers but I found these awesome monster stickers on Amazon that were even better! They paired really well with these neon colored party hats. This one was so simple and a big hit! I definitely plan to do this again with other party themes too. Keeping it just stickers meant less mess too.

 

Monster Bug Toss Game // Aidan's monster birthday party - tons of easy DIY decoration, kid-friendly activities, and adorable party favor ideas to save.3. Monster Bug Toss

I considered a bean bag toss but since that would need more room I opted for something smaller. Aidan has a lot of little plastic bugs (I bought this set of colorful counters last year when his bug obsession began) so that’s what we decided to have the monster eat. But you could use anything – other tiny toys, pom pom balls, crumpled paper “trash,” etc.

The full steps on how to create these (it’s just paint, cut, glue, done!) are on this blog post, Feed the Monster Game.

Coloring table // Aidan's monster birthday party was bright, fun, and stuffed full of awesome monster DIYs. Check out this giant list of easy-to-do monster birthday party decorations, kid-friendly activities, and adorable party favors.4. Coloring Table

I originally wanted to put a long roll of paper on the floor somewhere for kids to color but couldn’t figure out where that wouldn’t be in the way. So instead I just cut a piece big enough to cover Aidan’s toddler table and drew some monsters on it. I left a handful of crayons on top. It worked really well since it doubled as an activity and a place for kids to sit and eat cake. I used the Ikea Mala roll of paper that fits into their easel. I do like the idea of creating a huge wall mural for kids to color in when they’re a tad older. (We were nervous of toddlers and crayons near our wall.)

Paint-Your-Own-Cookies // Aidan's monster birthday party was bright, fun, and stuffed full of awesome monster DIYs. Check out this giant list of easy-to-do monster birthday party decorations, kid-friendly activities, and adorable party favors.5. Paint-Your-Own-Cookies

I also ordered sugar cookies from Magnolia Lee Baking & Sugar Art because she makes these really fun Paint-Your-Own cookies. She draws a design on the cookie using a food safe marker and then has these mini palette cookies with food coloring on them. Kids just dip a paint brush in water and then on their palette cookie and they can color in the image. Kids of all ages liked this one, though the toddler-painted cookies were not very appetizing to look at, hahaha. I left out a box of Ziplock bags so parents could take the painted cookies home if their kiddo already had cake. This would make an awesome party favor – either letting them paint at the party or just take home a bagged cookie and paint brush.

Adopt a Monster Party Favors // Aidan's monster birthday party was bright, fun, and stuffed full of awesome monster DIYs. Check out this giant list of easy-to-do monster birthday party decorations, kid-friendly activities, and adorable party favors.6. Party Favor Monster Finger Puppets

Our farewell gift was a Yippitee finger puppet topped with our free party favor tag template. I’ve taken lots of pictures of these bags all dolled up with bright candies and a finger puppet but with waffles, cake, AND cookies, I knew my friends would disown me if I gave out candy too. So I just tossed in a couple suction cup monsters that I bought on Amazon awhile ago (thinking they were not as cheap-looking as they are, haha) so that it wouldn’t be just one monster in the bag. I wish I’d gotten some tissue paper confetti or Easter grass or some other cute filler but hadn’t thought of it and of course left these for last minute. Still cute though!! And the kids were excited to get their own monster after seeing Aidan’s on his shirt and awesome cake. (Disclaimer: Yes, I know it was total overkill to give kids a handmade mask, sugar cookie, and finger puppet but I just didn’t want to give up any of the ideas! And I figured sharing them all would mean more inspiration for other monster parties.)

I hope this helps you plan your little monster’s next party! It’s such a fun theme you can do so much with. Enjoy!
