The first one is 8x10, where as the second is 9x12. I actually kind of hated the first one right after I painted it, but It's grown on me. the second was the exact opposite, I loved it until I looked at it in the mirror to reveal all sorts of errors, some were fixed, most not. Although I'm not to found of it, the surface was nice to paint on; my first time painting on oil primed linen. I'm now planning on buying a roll of the stuff for later use.
