I don't remember if I shared this in the "Dream Products" thread, but THIS is why one of my "dream products" is pocket pages that have pockets on just one side, but the other side is a blank 12x12 opening. OR pocket pages that are just one-sided to begin with, but there's some way you can stick on the pocket design of your choice to the backside. Since they're clear, you technically COULD scrap the same design on both sides, but there would be a way to easily stick a new design onto the other side if you wanted to make a different choice. I realize someone could easily dummy this up by sticking or stitching pages together, but I think it would look more finished if a manufacturer came up with a nice method for attaching everything.
I really dislike leaving things looking unfinished in my albums, even if the album itself is an ongoing project, and I don't like feeling like I'm stuck with a particular pocket design on the other side of the page. In the absence of my "dream product", I tend to either only use a pocket page in my traditional album if I already know what's happening on the other side, or I forgo the pockets and just stick my items or PL cards down to a blank piece of cardstock in the same arrangement as I would if I was using a pocket page. Even before PL was a thing, I often made pages of tiled 4x6 and 3x4 elements on 12x12 paper. I think I'd only need the actual pocket page if it was important for me to be able to get my items out again later.
