I framed up my brown canvas for Serpentine yesterday. Then I took out my instructions and started reading and looking at the photo that Ro Pace sent. The brown canvas would not work with my thread choices. I then remembered that Ro suggested I use eggshell, not white, as my canvas color. No eggshell in the stash, but I have a nice light blue. It shows as white in my picture, but it looks much better with my color choices.
It looks like the piece has canvas showing in one area-a lot of canvas. If my blues "clash" at that point, I will do something to make the canvas work.
