Fabulous, I’ve used it to mark my quilt, I’m a hand quilter. I use a brush dipped in water to wash out as I go. Big job if you wait till the end of quilting a quilt. Easy Peasy as you go. This marker works so much better than the popular brands, nice thickness, makes a clear mark, not fading down in intensity as you mark. My favourite, I’ve ordered a dozen to keep me stocked up. I’ve marked a whole quilt and it still show no sign of dying. 10/10 for me.
