Although my fiber page design isn’t terribly thick, the quarter inch drawer causes the pages to bow when the book is flat. The spacers provided with the photo album are too thin, so I made new ones out of quarter inch thick foam sheet from the craft store.

I cut the foam to match the old spacer using a large paper cutter, then matched the holes with a paper punch. The foam was remarkably easy to punch. Assembling my fiber pages in the book went much, much easier using these spacers and three inch posts.
