Still working on EZ's Pi Shawl, I'm up to the 3rd pattern (576 sts per round). I didn't want to repeat the same patterns again (1st and 3rd would be the same), so I found another diamond pattern in Barbara Walker's Second Treasury of Knitting Patterns. It's the Gothic Leaf Pattern on page 288 of my edition. Here's my chart to be used when working in the round. (Walker's directions assume flat knitting, so I converted to circular by removing 1st K1; and all odd rows will be knit instead of purled.)
I'm up to 576 stitches per round, which is evenly divisible by 16 :-)
No, I didn't swatch....
