Some of my stash is wool, but the vast majority is acrylic.

Also, as for the "it'll take too long," I can understand where he's coming from but that thought generally doesn't stop me. I figure if it needs to be done, it doesn't really matter how long or how munch energy it'll take, I just have to get started and work my way through. On the other hand, if I think the job is pointless, I may never start.
