Sounds like a trip to dollar tree is in order ! Find lots of coordinating party decor cheap i agree with other anawer aboyt using stuffed animals as centerpiece... if you don't want balloons you could make tissue paper flowers and tie to backs of chairs..etc. or even make coordinating mini cake pop displays or similar for centerpiece. Using those as the take home gifts for party attendees

Use the stuffed animals as centerpieces, get the different colors for balloons to tie on the chairs of the tables and the character color for tablecloths

you can have each stuff animal wrapped around a bowl of candy that coordinates the colors so guest can snack on them throughout the event and buy table clothes one color and confetti for the second. or even coordinate each tableware to the table which will make it easier when serving you can call ex: "goofys table... etc" good luck!

So I'm having a birthday party for my son. I was going to do Mickey Mouse themed but then me and my mom were coming up with ideas and I happened to look at her stuffed disney characters she has on her bed. She had Donald, goofy, and Pluto. I was like"wouldn't It be cute if each table was decorated according to each character?" She liked the idea but I need help. I want Donald's table to be blue, white, and yellow. Goofys can be black.orange, and blue and so on. The main table (with the cake and food) will be all mickey. Any suggestions to decorate each table?
