I’ve gotten a few orders from paper-papers.com but I also got some from letterpresspaper.com and frenchpaper.com. I found that it was cheaper to get some savoy from letterpresspaper.com and have it cut down by a local print shop. I also have ordered some holyoke papers from holyokedirect.com. I like them but way pricey. if you’re not in a super tight deadline, then I would get parent sheets from letterpresspaper.com otherwise, I think paper-papers.com have pre-cut ones.
so far, I’ve gotten a few sample packs of cotton and bamboo papers. I like Savoy, Lettra, Arturo and Legion Bamboo, though Crane’s colors were nice too. French papers are okay, but I prefer the softer paper myself.
hope that helps.
