I'm a painter and a quilter. DO NOT WASH!!!!! They have been shaded and you will lose all the shading, as that paint has been thinned. It is beautiful now,but not if you wash them. I would lay a thin cloth over them and press good with steam, let dry and then do your sewing, what ever you want to do. Also, if you frame them, you do want glass on it. The non glare glass with spacers between the glass and fasbric. If left unglassed, the material will deteriate over time and and the paint would start to deteriate and flake off.
