Hi! I just posted a layout with the pull tab a few days ago. In my gallery i is the 20,000 Leagues right side. On that one, I just added a back page that was the same size as the front. I measured where the pull out fit & the size of it & made sure I put the adhesive around where it fit. I also left extra room in case I messed up. I put a cardstock tab that I made by folding rectangle. Some people use those metal tabs. Or you can use a ribbon loops.
