What I'm wondering is if anyone has an idea for perserving the sketches? My paper is 9 x 12, a rather odd size to find slips for. I was just going to use a page protector (clear plastic) to slide them in, but those come in normal paper size, not 9 x 12. I don't want to laminate it unless I absolutely have to. Is there something I can spray on them, or a place I can buy page protectors from that run in that size? Any ideas are appreciated!
