I am in the middle of quilting my quilt top and I have realized that I am going to run out of thread. I have been using Sulky blendables 30 wt. #4091, but I can't find it anywhere and my quilting store is not sure when they will get another order, if they can get it. Does anyone know of another line of thread that might match up with Sulky blendables? I don't think it would even have to be an exact match but I do want variegated thread.
