how about sewing them together to create a bag?
GID paints can be found in lots of colors and varieties
you can also get glow in the dark powders and sprinkle them on freshly painted surfaces of mix them with white glue and "paint" them on.
We have used the glow in the dark powders for a lot of out crafting and fairy projects.
I've used GloNation, Deco Art Glow in the Dark, Krylon Glowz, Rustoleum Specialty Glow in the Dark and a few others. It depends on what project I'm working on.
Sia, which gives the best/brightest glow? Looking for something for a fun summer project for my daughters while my husband is deployed.
