I've made one using the same book and accompanying DVD. Loved the process. I used plain muslin as my "pallette" and then started to cut shapes and glued them to the muslin with a glue stick. Once I was sure that I liked that area I stitched it down with clear poly thread then moved on to the next area.
With mine I used all batiks ... that was just what worked out best for what I was creating - sand, sea, sky and a palm tree. I did add some thread painting to it as well when I was finished (in hindsight, I should have backed that area with a stablizer and thread painted it before I quilted it - but I did thread painting and quilting at the same time).
I definitely want to make another landscape quilt some day, but as of now ... too many other projects are competing for my attention.
