This has taken about 10 bags so far, and I find myself in the unusual position of wishing I had more plastic bags in the cupboard under the sink. Theoretically I'm knitting a bag. What else would you knit with bags?. It's a bit hard going because the yarn (or 'plarn': geddit?) is a) not very elastic and b) not very slippery. At least I get to use my funky raspberry ripplesque needles.
