This is my version...
...not exactly the same as in the book ~ I used some heavy cotton webbing I had for a single strap handle. The cream-colored felt was from my scrap bin as well {try not to notice that the crosses are starting to pill a little}.
I saw quite a few projects in Zakka Sewing for which I would love to make time...you can see a gallery of some of them here. *Edited to fix link ~ sorry!
