I often would draw in square paper (and in Europe artists are not restricted to what format to use, as long as it is good)...comics and other stuff and prefer it,...I am glad you broke the rule in America (even though I have seen it in small press)...now that Strathmore is doing the paper {I hate cutting my own} I will use theirs, I wish they made it also in 8 x 8 as other companies such as Sennelier
