I think that might be it. I might move one "L" piece, but I think the squares are set and they were my major concern. I laid it all out last night, took some photos, shuffled things around, took some more photos, then made sure everything was secure before throwing it all into the washer.
I suffered a recurring brain fart while knitting the strips, breaking off the yarn at the end of about half of them, rather than casting off -- and, of course, not leaving a long enough tail to cast off. I used yarn to hold the stitches, mostly, and needed to make sure that ALL the ends were tired and secured. The hand wash cycle doesn't even take a half-hour, so I was pinning out pieces before long; first watching a little football, and then Project Runway I cast on a little something to use up some yarn.
It was an entertaining evening.
God I love this crazy thing!
