I read the article about using artist canvas to hang needlework, too. The canvasses I've seen hung without framing were flat to the wall....so picture wire and eye screws would be a necessity for needlework....would that spray stuff they used to make to protect fabric work?
While I agree that this would be a less costly way to frame/hang your work, anything I spend a year working on deserves professional framing and is going to get it. The artist canvass is a great idea for seasonal and fun stuff....it would be great for modern stuff, too....heck, I just like the idea....if we can figure how to protect the needlework long term.....
Wonder if they make a box cover....kind of like they used to have in movie theaters for posters and stills? Just thinkin'.....
