I recently ordered a set of Derwent Inktense pencils to play around with and some textile medium...while I'm waiting for them to arrive I had a few questions. For those that have used them - can you stitch through the color on the fabric after you've painted with them? Or does it build up like regular paint to where it cannot be stitched through? I love Sherry Rogers-Harrison's work where she stitches out a design and then goes back and colors...but I'd like to do some paintings on fabric then go back and quilt them. I've experimented with several different paints but all built up to a thickness that really didn't allow for stitching afterwards...and I have a small home and workspace and don't really want to get into dyes unless I have no other option.

Thanks!
