The 6x12 pages are my favorite size beyond the usual 12x12 layouts in my albums. I like to use these for a picture plus a list layout, to extend a 12x12 layout without using a full second page, and to introduce a new category in in the album.
I like the simple design of page protector. I don't want any style on the page protector to detract from my layouts/ photos. I only gave it 4 stars though, because I would like to see a little reinforcement at the ring holes. My toddler can be pretty rough turning the pages!
