Has anyone ever used a carpenter's chalk line to mark a quilt?
I have a quilt top in progress that I will want to mark a lot of long, straight lines for quilting.
When working with drywall or planks, if I want to mark a long straight line I will use a carpenter's chalk line, which is basically a string covered with powdered chalk that you can snap and it will leave a line. Has anyone tried this before on a quilt top? Do the chalk lines come out in the wash, do they leave excess chalk powder?
