So...what I needed was an old book...not a beautiful one because it was to be overpainted and of course some old worn jeans I didn't wear anymore.
I chose these two wonderful Lynne Perrella stamp sets : LPC047 and LPC048. I also chose the colour combination...that was easy because it's my favourite: blues/turquoises and rust.
Now the fun part starts! First I covered the book cover with a layer of gesso to be sure the paint doesn't soak in too much. I dried the gesso and painted big parts variably with blue and brown paints. I used PaperArtsy Fresco Finish Chalk Acrylic China and Toffee. I love them, and I love the combination! I didn't work very elegantly here, but that's not necessary because almost everything will be covered.
Bringing everything together! But first, while I was poking around in my studio, I found these beautiful metal corner-pieces...perfect for this book-bag! Using tacky glue, I glued them on the upper corners.
