My daughters haven't learned to swim yet, but we did arrange for them to have weekly art lessons this summer. One of the final projects they did with their teacher was tie dyeing. Buried in the laundry room, I found some clothes to send along for them to dye. They brought home their wet handiwork in a bucket. The next day I un-banded, washed, and dried their rainbow creations. Above are some of the results.
I would like to find some more clothes to try this with at home, though school starts in a couple of weeks. We'll see. Have you ever tried tie-dyeing? Or does the mess intimidate you?
