Hi hi Lilly, We've done this several times with varying success until Dharma. Check out the website Dharma Trading Co. They have great kits for tie-dying!! Everything is included but the creativity and the shirts, they also sell those (diagrams, instructions, the works.) The whole company is super to work with ( no, no connection or kick-backs) Then just be sure to follow the instructions to the letter and put in the little bit of prep work ahead. We did this on a family reunion vacation and it was a huge success with all ages. Dharma is also a great resource for the t-shirts and other dyables. Start out on the plain white tees and be sure to read the reviews for sizing and quality, etc. for your shirt choices, or just go to buy locally where you can see and feel the matrls. if you don't have time to ship well in advance and return, or buy used/resale/thrift store t- shirts, all cotton, prewashed (without fabric softener) and preshrunken. Dharma's colors are fabulous and stay bright, again, when following the directions. Be sure you have access to lots and lots of cold water for the thorough rinsing. Take several 5 gallon buckets and do assembly lining, and long sleeve rubber kitchen gloves, if desired. Take a clothes line and clothspins to dry them hanging in the trees. We are planning to do this again with our now teens this summer. Hope you enjoy it as much as we do! ; ) happy hippy art!
