Our biggest project was aprons. We decorated aprons for friends and family. I outlined words and shapes and the boys colored them in. We usually didn't do more than one a day, but the boys loved it (Except for when they didn't, which was when the sweatshop rules were enforced. Ha.) We got fabric markers and aprons at Michael's. Here are some pictures.
Another project was making gift bags for all the gifts we gave. Blank white bags at Michael's, crayons, tissue paper at Walmart:
I also decorated some wine glasses as gifts. The idea was for the boys to decorate them (as is the nature of sweatshops), but that didn't go too well so I ended up doing them. They were okay, but not worth the time and expense of the glass paint and markers.
