I've got a small assortment of the basic "colored pencil" style of dressmaking pencils, and I hate them. They don't mark the fabric unless I mash it hard, and then it makes a fat line and distorts the weave of the threads. They do wash out, but they're basically useless if they're not going to mark easily.
I love handquilting, and I'd like to incorporate more complex stitch patterns into my quilts (I'd prefer to draw them on, rather than stenciling). I would like to find a pencil or chalk or something that can mark in a fine line, is *not* air soluble, and will wash out (obviously). I don't trust the washable ink markers, but if you can reassure me that they'll wash out completely, I might give it a go.
