OK, I am going to throw a question out,last night I told my granddaughter I would ask.
She is making her first REAL quilt, a large throw size, and has for the first time done lots of piecing, and got brave to try some FMQ. But, she is still having a hard time just free wheeling, so I have been using a white water soluble marker to give her an idea where she wants to head with the part she is quilting. The marker is sort of hard to see on the fabric, so we were discussing easier ways to mark the quilt. Anyway, my question.......
Since Koolaid will not dye cotton fabric, but only stain it temporarily, could a line be painted on the fabric to mark the quilt, then rinse out the Koolaid? Of course it would be a good idea to test it out, and see for sure on the exact fabrics that will be used, maybe a sandwich of the exact batting too. But, I wondered if anyone had ever tried this?
