2 -12x12 scrapbook papers (depending on the size if your book)
First measure the height of your book + 1/2 inch and cut your papers. Next measure the width of the spine of the book you wish to cover.
You will overlap the two pages to the width of your spine and sew together from top to bottom. I used a zig zag stitch.
Now line it up with the spine and fold your paper over the front and back covers and crease. You will sew the fold down by sewing all along the top and bottom. When sewing, I stayed as close to the edge of the paper as I could.
I am now staring down my bookcase dreaming of it filled with pretty coordinating books ; )
