Too often, I have found that chalk marks disappear, on larger quilts, because of the movement. And then I need to re-do them part way through. Or just mark a section at a time. Thus I am always looking for a new possibility.
I have heard of these Clover markers/pens and the patience required to "see" their marks!
Do their marks stay "put", as you work with the quilt?
How do you remove those marks, once done?
