I realized I haven't shared any photos of my Tetris Afghan-in-progress lately, so here are two.
It's not really that wobbly, just laid out crooked. And look at all those damn ends I'm going to have to weave in.
I also finished my second full spindle of yarn, 21 yards, so that makes 33 total! I still have roving left to spin, I don't know how much yarn I'll end up with.
I found out that someone else has made a Tetris blanket before!
Craftster member Zeropixie has a crocheted afghan, posted only a few weeks ago.

Hers looks awesome, mine is going to be very different but I hope it turns out just as lovely!
As far as I know, I'm the first person to knit Tetris. I got the idea one day when looking through a knitting book and one of the patterns reminded me of Tetris blocks. I'm making up my own pattern instead of using that one (it was a one-color piece of fabric with some raised stitches, not like mine at all).
Each small square is knitted using a stitch I call the "knotty stitch"; I've never heard a real name for it. I posted a tutorial on Craftster.org if you're interested, go here to see it.
I then crocheted (my first crochet experience, woot!) a single-crochet border around each square, and joined the squares into Tetris blocks with slip stitches.
Here's two of the finished blocks:

Here's the first 3 slip-stitched together:
(my feet shown for scale, hehe)
It's not blocked at all, hence the general wigglyness.
More pictures to come as I work!
