I call it "spine filler" ... what is it really called? It is the strip added onto the posts of a post-bound album to take up the extra thickness required because you've put several layers of cardstock/photos/paper/embellishments in your layout. A package of sheet protectors will have a couple of strips included (made of chipboard) but they are never enough. What do you use? Do you just get some more chipboard and cut out a bunch of strips, or can you buy a big package of them? I don't know what to Google because I don't know what they're called!
And has anyone seen any 8.5 x 11 format albums by any brand besides Pioneer? That format makes so much sense, but that doesn't seem to be a size that the album manufacturers produce. How odd.
