I used to sell Tri-Chem back in the 70's had NO idea they were still in business. My mother sure painted some pretty things with the Tri-Chem paints she was better at it than me. Have No idea what ever happened to my paints must have sold all them at a yard sale. I do remember that the trick to getting them to last on fabric was to heat set them and the color would stay bright. They probably have improved the paints a lot since then.
I check out the site and see they still sell them on the party plan.....and they have a Lot more product than what they did when I sold it. Will have to check them out futher.
Thanks for the memories.
