We have had a bit of trouble finding a place where I can prop the frame up securely enough to work on it. I tried several options in the living room; Dan and I experimented with step ladders and easels in the kitchen; finally I took it to my bedroom and discovered that the ugly plastic crates I keep teaching stuff in have a kind of lip on the edge. They are also so full of teaching crap that they are really heavy. Lean the frame against my window - natural light from behind the canvas is great! And the lip on the edge of the box holds it up.
That orange square check thing is a seat pad from one of our dining chairs which fell apart. Dan fished it out and has given it to me as my Official Rag Rugging Kneeler Pad. So that's why we never threw it away!
