Well, not entirely self-designed I guess, as I borrowed heavily from the hourglass sweater from Last Minute Knitted Gifts.
Once upon a time, I knit a Central Park Hoodie, or at least, the back, fronts, and sleeves. I decided it was time to seam it all together before doing the hood. Lo, then it came to pass that I made a horrible, horrible mistake, got angry at the sweater, and ripped it. From the ashes of this I decided to create something seamless, and the Phoenix sweater was born.
Due to a mysterious quirk of gauge *ahem*, it's too small for me, but perfect for my sister Katie, America's Next Top Handknit Sweater Model.
I used the embossed twining vine leaf lace pattern from Vogue Knitting. I also originally wanted to make the raglan lines stand out, but couldn't figure out how to do it; I wanted the appearance of a seam, to make the stockinette body and reverse-stockinette sleeves look like they'd been sewn together from other sweaters. But I like the little purl channel I made instead.
Oh, and it's good ol' Woolease.
