Remember tri-Chem (I think that is the name if it) paints? They were paints in tubes that were popular to make tea towels, etc in the 70’s I think. Anyhow a client used them to color these Hawaiian kids and then she made a quilt out of them and wanted me to quilt it with traditional echoing. It did pose some problems with some of the blocks but I worked it out on my iPad with procreate and found that it would work with a few modifications (used monopoly thread in the pictures themselves where I didn’t want to echo).
