Thanks so much to Ella at Kampfhorn. She left a link (to Photojojo) for directions to make notebooks. I gave it a try and it worked very nicely!
I did tweak the directions just a bit. I used fabric to cover the bound edge. For most of the pages I used an old calendar.
This notebook is going into my bag for when I want to journal when I'm out and about. If it holds up well, I'm definitely going to be making more.
