For some time now, I have been wondering what to do with all those little bits of wood that come with canvases. I know they're supposed to be used to hang the canvas... but for the life of me I've never been able to work out how they actually DO that!!
Instead, I have used them in a picture! I roughly painted them in children's paint (and I was assisted by my daughter), and then I glued them onto the black painted canvas using superglue. Because the bits of wood have angle edges, I made a zig-zag pattern with them where possible.
