My friend has a plastic tool especially made for marking as you go, for hand quilting, she can't remember the name of it, no brand name on it, and she has had it a long time over 25 years she said, the mark is only a crease which eventually goes away by it's self! I am quite taken with it and wondered if there is a similar thing on the market for todays quilter, especially since I am enjoying hand quiting.
My friends marker tool looks a little like a plastic pate knife!
