Here are some longies I knit last weekend. I used the Juju pattern from Knitty. I added holes for a drawstring instead of bothering with elastic. The yarn is Paton's Classic Merino that I got on sale last winter. It took 1-1/2 skeins.
Lanolized and ready for diapering! She did get up to standing by the box, but it kept moving away from her, so it took a little while. :)
