My niece and I have been making scrapbook pages over the holidays. She wants to use all the stickers she has, none of which are acid-free. Then she wants to use my expensive scrapbooking supplies as though they are el-cheapo brands. They're all the same to her. Will her stickers really ruin my lovely pages? She's determined to use stuff she has been collecting. I want to let her do what she wants, but I don't want the thing to fall apart before she becomes a mother herself.
