I am using these with the WRMK 8.5 x 11 3-ring Album for a school memories album. I take photos of my daughter's art projects and keepsakes (then throw them away) and slip the photo in the page protectors. It's less bulky than saving them all! I also like that I can mix up the sizes of page protectors in the 3-ring album as well. These would fit in a 12x12 three-ring binder / album as well. Very versatile. They're well-made and I'll buy again!
This past winter I used these page protectors, as well as others, to create a baby book for my sister-in-law. Love them. She isn't much of a scrapbooker, so now all she has to do is slide in her own pictures and journal.
I used these sheet to protect my husbands Hockey Card collection. After having each player sign them we are able to preserve the cards and still able to look at the card and stats as desired.
