I use the painters tape for marking for cross hatching when quilting. I use it when I embroidering; when the roll of stabilizer is a little short in the hoop I run painters tape down the side of stabilizer and then hoop it. This gives me more to hold onto when stretching it tight and then I can tape it to the side of the hoop to keep it tight when embroidering. I use it to keep my thumb tack in place when using my "makeshift, homemade" circular guide. It works great and then I put a pencil eraser on the tack to keep the fabric in place while sewing. Sometimes I mark my machine with the tape when I have a certain width of seam that I need to be on one side of the presser foot while sewing.
