Here are some pictures of one of the Bible cases I have crocheted. I used Vanna's Choice yarn and a size G hook for this project.
This was a very simple crochet project. All you have to do is make a chain long enough to fit along the cover of your Bible, HDC in each row until you have a good fit, sew the sides together and add handles, a button, and a strap to go over the button.
Have a wonderful day!
