Linda & Laura Kemshall recently had video clips on their DMTV about making altered books. I found 2 old books in second-hand shop in Galway a few weeks ago that I'm using. 1st stage is to reduce the number of pages in the book by glueing pages together, adding stitch to the pages, and then adding gesso or gel medium to the pages. It's taking a while to get the pages prepped as you have to wait for the gesso or gel medium to dry properly before adding colour to the pages. So I've been putting a coat on the pages every time I get a chance, but haven't got very far at the moment.
I'm going to use one of the books as a sketchbook for an upcoming quilt project that I'm working on.
