I was reading a post about making perfect crosshatch quilting marking with the Clover Hera Marker. I am sure some of you have used this in the past, so tell me, does it really mark so well, that you can actually 'see' the mark, when you are quilting? My eyes are old and I would be doing larger than 1 inch crosshatch on bed quilts. Will the 'crease' stay with all the handling of a larger quilt? what do you mark with than I would be able to see?
