Well, maybe not a purse but a sketchbook from "reclaimed" trash. I bought a sketchbook and it came in a slip case. I threw the slip case in the recycle bin but later fished it out again because it was made from heavy weight box board.
I slit off the top and bottom leaving what looked like a book.
I made a 10 signature insert and coptic stitched it with dental floss since it was waxed and would never show.
I covered the old book slip with some of my paste paper
I reinforced the spine of the book insert with a buckram "patch" and glued the insert in the book cover with gell medium.
Voilla', a new sketchbook
