I listened to a podcast interview of Judy Wise. Rice Freeman-Zachary did the interview and posted a link to it on her blog. To hear the podcast, go to Rice's blog and look in the right hand column. It's great.
In the interview, Judy mentioned making a 4X4X2" accordion book that she found out about at Journalfest this year. See Judy's pictures of this book style on her blog. Scroll down toward the end of the post.
I covered my book with canvas. Just make a number of accordion fold sections. I began with Stonehenge art paper that was 30" by 22" and I got four accordion fold sections from that. Tape the back edge of the sections with small bits of tape. Glue on the cover with thick gel medium. Let dry overnight. There it is. Judy painted faces in her little book. I am not sure what I will do with mine. Have fun I hope.
