I am seriously considering making Elfin Bride by Jennifer Stafford, but there is a lot of knitting done on the bias so not only stitch gauge, but also row gauge is important. (It is a really neat construction if you have a moment to flip through the gallery.)
Plus this is sort of like knitting from my book stash, which is always a good thing. How can it only be sort of? Well, the author includes pictures of this sweater in Domiknitrix, but they ran out of time in space to put the actual pattern in. So this pattern is available for download at the website (linked above) with a password from the book.
I has been quite a while since I finished knitting an adult sized sweater, yet I have a couple of sweater quantities of yarn in my stash. I would like to be finishing more than one a year until I run through the sweater-quantity stash.
