I just got Dfr's "mystery maybe-wool knit," as she mentioned in her Reveling in Fabric post. I have absolutely no doubt that it's wool. ...it's also not a knit! Here's a closeup of the fabric, it's a wool tricotine: a worsted wool 63 degree double twill weave. Just like the other worsted wool tricotine I have, but in a different color.
I managed to get quite a good closeup of it, with a piece flipped over so you can see both the front and back of the fabric. If you follow the image link for the closeup, you can then click "original" to see the larger image; the details of the weave are very nicely visible. (Although it's quite obvious even from the preview picture..)
I'm going to have fun with this one!
