It goes through different methods of fabric manipulation like gathering, shirring, ruffles, flounces, godets, pleating, smocking, tucking, cording, stuffing, quilting and darts. It contains black and white photos, as well as drawings, of each type of manipulation. I'm not sure how comprehensive the instructions are (the visual instructions aren't great, so some sewing skill is required), but I'm feeling totally inspired nonetheless.
Tonight I made this birthday card for my mum (happy b'day mum!). It's fairly simple - knife pleats with a couple of yoyo's stitched on, but I'm loving the 3 dimensional aspect of it. I've added a bit of thin sashing to frame it, then just folded the edges under and sewn it to a piece of cardboard (unfortunately, it's a piece of yellow corrugated cardboard, but hey - when the creative inspiration hits at 10pm, you have to go with it, right??)

I can imagine a quilt top in my future with 3 dimensional blocks, each different but pulled together by the fact that they're all made from a single colour....
