So I'm making an (digital scrap) autograph book that I plan to have printed at artscow (or somewhere else, I don't really like their 7x5 cover). I'm wondering if I should leave the left hand pages blank for pictures. Is there anything like a stick on picture sleeve that I could put in the books or would I have to glue/rubber cement the pictures in? I'm not much interested in the gluing, but if some sort of sleeve existed, for some reason that makes me more interested.
