We're going to Disneyland next month and I want to create different autograph items for my girls. 2 girls want pillowcases, DD 17mos. I think I want to make her a cloth book for autographs. What fabric would be best, regular cotton? Sharpie's for autographs? Will the autographs bleed? Is there a free pattern anywhere for a cloth book? If possible I'l like to add vinyl pages to put pictures in later.
