2.) Trace and cut out the same measurements above onto 12-17 sheets of paper of your choice. (I used creme colored parchment paper from this Barnes and Nobles notebook. It has a great texture that works well for sketching and for using gel pens.)
3.) Fold all of the cut out pieces of paper in half width wise and insert them within each other to form a booklet. Be sure to have your cardstock cover on top.
4.) Staple the spine of the booklet together buy using a long reach stapler.
5.) And now you're got yourself a new midori passport insert!
I like the idea if making my own inserts now as it gives me the flexibility to use whichever paper I like. Plus, when you're drawing and journaling on such a small amount of paper, these inserts can quickly fill up, so this is another way to help reduce my crafting costs.
