I took an SEI class about a year ago, and they showed us how to use these in a 12x12 scrapbook, to add more photo's to your layout. Its a must have. It goes out of stock pretty fast, and can be hard to find.
These are perfect for the ABC book I made for my 3-year-old DD. She can use a dry-erase marker on the letter tracing pages and just wipe them clean to use again. Wonderful! :)
A well produced product - the sheets are well sealed and i have not had a one come apart or tear - even after placing and removing projects from them several times...
...if you have the little album. I prefer this mini album over others because of these page protectors. Very easy to insert too!!
These work so well when you have multiple pics for a subject!
