Well, what I have used here is basically an old hard cover book, which I purchased from a local flea market. I bought this for RM5. Not bad. You will need to rip-off all those pages out from its cover.
Glue together at least 5 or 6 pages. This really depends on your needs.
This was how raw it looked before I started to work on it (below). The edges have been partly distressed with Ranger ink. I have used Vintage Photo here.
So, I do hope this altered book will be an inspiration for your next crafting project!
