I figured out what to do with some of the larger leftover pieces of foam from the sushi costumes. I'm going to make some large blocks for Monkey out of it. I bought some bright fleece tonight and I'll sew it into cubes to slip the foam into. Sure older brother BugBoy will turn them into projectiles, but at least they'll be soft.
It would be faster to take the cut fabric over to my dad's to use the sewing machine, but I'll see how long it takes to sew by hand. Plus I've got these nifty callouses on my right thumb and forefinger so I may as well keep it up. It that goes well I might try making a car with wheels that Vecro® on.
Monkey's first birthday is Tuesday, so I hope to have them done for that. I'll take some pics when they are done.
