I made her a rainbow cake and cupcakes. We set the cupcakes on paint palettes and placed sprinkles in the trays which allowed the children to decorate their own cupcakes. I also made "paintbrushes" by taking pretzel sticks and dipping them in chocolate. To stick with the painting theme, we dropped by our local Lowes and picked up various paint chips and created holders for our napkins and eating utensils, then we used the left over paint chips for decorating the tables.
We got the acrylic paint and the pinata from Walmart as well as the tableware.
We picked the canvas' up at Michael's and I ordered the aprons, paint brushes, and palettes from Oriental Trading. We let the children take all of these home with them, as well as watercolor paint sets for thank you gifts.
Everyone seemed to have a really good time, especially the birthday girl!
