One of the techniques I did from Kim's book was machine smocking. You have to be a lot more exact than I normally am with Kim's techniques but the finished look is well worth the measuring and marking. I'm practicing these techniques on small projects and would love to make a quilt using some of her styles as the blocks. I've been playing around with upholstery fabrics in some of my wall hangings and the fabric folding works just as well with thin upholstery as with cottons. I did some experimenting on an ATC.
I have bought fabric to make my new kitchen curtains, which is just going to be a topper and I'm thinking some folding will end up on my windows.
