My husband and I recently collaborated on our own DIY coloring book. I had done research on papers and read that 64lb cover stock was a great choice especially if you plan to use color pencils or crayons. We found 67lb 11x17" cover stock at Staples and ended up ordering more online when the stores didn't carry enough. The ordering in store and delivery was easy and fast. The paper really holds - much sturdier that zerox paper and our printed designs look really good. Our coloring book pages are two-sided and we were thrilled to see no obvious bleed through of the images. There were some minor specs in some of the pages but that's to be expected as part of the paper-making process. It's a bit tricky to fold without getting wrinkles so I recommend getting that done professionally (along with stapling) rather than trying to do a large order yourself. If using an erase to clean up ink/printing smudges use it gently to prevent surface wear. We are very pleased with this paper and it was also more economical than higher end presentation papers. It also looks like nice paper for DIY announcements artwork posters and more.
