My kids and I are making our own autograph books and we're wondering if autographing on laminated pages is a good idea. We'd use a sharpie...but as a teacher and mom, I can see that going badly pretty fast. We were in search of 5 x 7 page protectors, and we we'd pull out the paper to be autographed, but that size is expensive for the amount of pages that we'd need, so laminating seemed better, since we have all of the supplies to do it. Any advice?
