I'm about to donate a bunch of my sketches to a fundraiser at our therapeudic facility (twenty), but the problem is that I use cherry-wood pencils with soft graphite/charcole. I use textured medium weight paper, but they tend to smear a LOT. I'd really hate for someone to pay ten dollars for something, only to have it ruined a few days later because a child touched it, or they pressed it against something.
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!
