I've been wanting to try a 6x12 album for some time now. Here is the outcome. I used chipboard to make my own book, then I bound it with my Bind-it-All tool. The book has 6 pages, 12 sides. I used papers and things from Storytellers Club (January kit) which I had received as part of a DT project (www.storytellersclub.com). The color palette was browns, blues, oranges, red. Somehow, it works!
I also used the PageMaps (www.pagemaps.com) 6x12 sketches to help with ideas for building each page. I added lots of lumpy flowers and buttons, and was pretty liberal with the ink! Here are a few pages for you to look at.
