I tried my hand at stenciling in quilting designs into my new quilt and used this rolling chalk that I found at Joann's. It brushed off of the fabric scraps fine. But when I went to brush it off of the quilt after I'd quilted, it didn't come off of two of the fabrics. At first I thought it was trapped beneath the monofilament thread I'd used but it's on either side of the thread. So, I got a wet washcloth and tried to wipe it off since that's worked for friends. It didn't work for me. :cry: I've tried putting it in the washer on a rinse cycle, twice. Then I tried laundering it with soap and even another time with Shout! Nothing is taking it out. One of the fabrics it's on is a tan and the chalk is yellow so it blends all right but the other fabric is a dark purple! Any thoughts or ideas to help out?
