Can't wait to use them. I am doing pages with trip things and this fits the brochures of places we went. Just need the seat time to do it now. Awesome way to add variety to page setups when there are paper that you like to be saved but need to be seperated d/t acid free papers.
I have purchased a few 3 ring 12x12 scrapbooks. I use these photo protectors to sort my stickers and embellishments. I have albums for animal, baby, alpha, travel etc. It is so easy now to see what I have and to find what I want.
When you stack three 4x6 photos like that with the seaming inbetween, you get a side pocket that's more like 12 3/8" long inside of 12". And that means your 12x6 paper that you cut will be too short and apt to fall out. I've been putting cute scrapbook-y clips on the outside of the page protector to hold the side paper in. It does work great for brochures and other things you want to keep off of your photos. Works great mixed with other page protectors in a d-ring album. I will likely buy these again even with the measurement problem.
