I found these when looking for some printable books/bookmarks of the Bible (I'll share what else I found in a minute!). Meet Penny is a blog dedicated to helping us homeschooling mamas (i.e. those most likely living on a single income) has shared some printable Bible book cards that you may find useful. Since they're printable, you can do with them whatever you want: laminate and turn into magnets; laminate, punch a hole in the top, and put them all together on a metal ring; and more.
Oh, and these were created in order of the books of the Bible...which means you can glue them together, THEN laminate (I seem to have a thing about laminating!), and proceed with any of the above ideas. WARNING: IF you choose to glue bits together before laminating, DO NOT cut into anything you've glued together. Otherwise, it'll all come apart. (Ask me how much experience I have with that one...)
