I *love* the foam tape idea, will have to try that. I just use hermafix and cardstock. Really any of your tape runner type adhesives will work fine. I wouldn't recommend a liquid glue like zig or sailor, and hermafix dots would be a last resort for me. But the tabs, or photo splits, tape runner, etc anything like that is good. If you have a lot of stuff, one thing you can do if you won't want to use foam tape, is when you go to adhere your pocket down, put some scraps of cardstock between your pocket and the background paper, that will add a little give so you can easily slide things in and out of the pocket.
