In case you're coming in on this mighty miter undertaking late, or have lost recall of our ridiculously drawn out project, my sister and I are in the final throes of our collaborative throw.
We finished sewing the squares into larger squares, then into strips of larger squares. We were just about to join two halves Sunday morning when Lulu figured we could knit edges simultaneously before joining them, and having to shuttle the whole project back & forth for the long sides, when only one person can knit on them at a time. Clever, eh?
We're cautiously optimistic that this will be a Valentines Day gift. Meanwhile, we're still considering tube dress potential.
