The wolfe canvas is very wavy. It took me three times to get it straignt on the bars. I stapled it twice, and then ended up using tacks on Evertites. I don't know if it is the paint or the shipping that has caused this. I highly recommend using Evertites. It's still a little wavey, but I think it will be ok.
Does anyone have advice on how to handle wrinkled canvases?
