Quilting Pattern Guide - Vertical Columns

This is a Quilting Pattern Guide that my wife asked me to make. Her current pattern book is all about vertical strips, and she wanted something so that she could see one column at a time. Designed it with slots that work with her favorite clips. These clips are fantastic, and can be found here:

I used Gorilla Glue to combine the two halves. I don't have any long term results on how well that worked, but it seemed sturdy.
