I made this scripture case a while ago for Rachael's baptism. I got the tutorial off the Polkadot Chair blog.
I really liked the way she did this bag but I did different sizing because I didn't realize at first that she made hers for compact scriptures, even though she said it right at the beginning.
And you really can make it reversible. If I had thought of that I would have sewn things on a bit differently.
Anyway, It was a really fun project and didn't take any time at all.
