I have tied dyed for years, back in the 60's until now. The rubber banding is the fun part. You should let them each have a pillow case and shirt to rubber band. You can use wax from a candle before you give it to them to put their name on it. It acts like a resist on the dye and will make each one personalized and stop some arguments. Melt the wax in a double boiler and use a paint brush to put it on the shirt/pillow case. When the dying is done, use paper towels and an old bath towel on top and under the wax. Then turn on the iron and iron the area with wax until the wax is gone. If you don't want to do the wax, then you can use a permanent marker to put the names on. I would let them rubber band it and also paint with dye on the items. Be sure they do not have on any clothes that their mothers would be upset about getting permanently stained. They can use the dye to paint something before tying up the stuff. Be sure they put vasoline on their hands before the actually start to play in the dye. Not a thick layer, just enough to block the dye from staining their hands and around their fingernails. I would dye the shirts outside, it will get spilled, slopped, sprinkled, flung, and accidentally dribbled all over the place. They won't do it on purpose, just part of the age and excitement. Outside will have a little more freedom and will make it more fun. Dye them then let them dry before taking them out of the bundles. If you buy one of the tie dye kits it will give you all the individual instructions like making sure you use vinegar so you set the color etc. Let the kids cut the rubber bands off outside as long as they have protective eye wear on to protect their eyes. You can make a game of cutting the bands, set it up to see who's bands go the furthest, straightest, highest, etc. They have their turn one at a time and that way you can control the pandemonium and have some fun also. If you have any more questions, please let me know and I will help you out.
