- Paint, we used red, blue, and glittered acrylic craft paint
- spiked squish balls (ours came from the dollar store, I’d recommend one for each color)
- white paper plates or bowls, one for each color
- cardboard or something to place in between t-shirt layers (sometimes we use lids from plastic totes)

I love this idea it looks great!
This look awesome! What a great idea!
What a fun project!
