Every summer our family gets together and creates beautiful tie-dye T-shirts. We have fun together and then have the extra bonus of keeping a shirt to wear all season long. Tie-dye kits are available at most craft stores. They are a bit pricey, but I keep watch for 50% off coupons and purchase the kit at that time. I have found that the boxes of dye, such as Rit, do not do as good a job.
Tie-Dye Tip: The kit I bought this year had a large assortment of colors to use. To make color choice easier I numbered the bottles with permanent black marker, did the same on an old T-shirt, and put a splotch of corresponding dye color on top of the marker number. It was a great guide to the color choices available. The color guide won’t be wasted. I’m going to keep it to wear when I paint with acylics.
