It is time to give an update, but first a questions:
I am comtemplating crocheting the squares together instead of sewing, would that be possible?
The Salpekar square is one tough one. I really like the square except there is too much finishing and ends to weave in for my taste. It was a challenge.
Campbell, 3rd time is a charm, the first attempt ended with the cast on being 4 inch too short, the 2nd went well except I joined the cast on twisted. You will get a very cool Moebius square, unfortunately unsuitable for an afghan. For picture see my blog on Jan 5th.
Two more squares remain, well they are actually knitted and currently being blocked, but it is too dark to post pictures. Thus, it is time for blocking the other 18 squares and knitting the border... I am using a 2x4 foot cork board (floor tile?) from Target as a blocking board. It allows me to block 4-6 squares at a time.
