I purchased books from a second hand store. Look for books that have a fabric covering to the outside.
Take sandpaper and sand off the lettering on the spine.
If you can't get it all off try
-painting the spine like I did with the black one
-using twine or ribbon to cover it (purple)
Get creative. Call your books Potions, Brews, Curses, Spells, Poisons, etc.
Decorate using different methods.
-I put stickers on the purple book to spell out Curses. With silver paint I stippled over the top, let the
paint dry, removed the stickers.
-Draw your lettering or design with a glue pen (can be found in scrap booking supplies) and sprinkle
glitter over the top of the glue.
-Take a pair of scissors and scrape the cover so it looks like fingernails clawing the book
