This setup spells ROAR in giant lime green letter balloons hanging over the party table. Jungle leaves, a dino cake and treats sit below, and the big letters make the whole table feel like a jungle sign. It looks bold but uses only a few balloons.

Letter foil balloons are one of the easiest DIY decorations. Buy four large letters, inflate them with air, and hang them on a string over the table with tape or hooks. Add paper leaves around the edges.

This mom built every part of this dino setup herself. A blue panel backdrop with dino art, balloon clusters in green and orange, and a big number five come together in a full party wall. It shows how much you can make at home with time and planning.

Start with a plain panel or foam board and paint or print a dino scene on it. Build balloon clusters with a cheap garland strip, then add a number made from cardboard or foam. Do one piece a night.

This colorful topper shows a red dinosaur with a happy birthday message on a blue and white cake. Simple shapes and bright colors make it easy to read, and it adds a fun focal point to the cake.

Bright toppers are great for younger kids. Print a dino clipart on card, cut it out, and back it with a second layer for strength. Tape it to a skewer and push it into the cake.
