I found this kit from Hobby Lobby ($12 with a coupon. It comes with a lot of product, I think I have enough to dye at least 8 small shirts). The kit comes with the dye, bottles, rubber bands, and gloves. In addition, you'll need shirts (or whatever you're dying), an old towel or garbage bags, and aprons for your kids. The kit comes with directions, but I thought I'd share a few additional personal tips. To prep your shirts, get them damp. I threw ours in the washing machine in hot water to preshrink them.
