Wow this was a quick knit! Probably largely because I really loved the process, it was measured out in lovely rewarding portions, & I was knitting as a way to decompress from various stresses.
Slight modifications:
1) I basically knit wedge 2 the same as wedge 4, as far as the striping-- just wanted less garter ridges, to make it more uniform + be conservative about using up yarn, as I was a little worried about my yardage (justifiably so, as it turned out!)
2) You might notice that I did a couple extra rows of MC in wedge 1… it wasn’t deliberate, & I didn’t notice it at first, so in the end I just made my last MC garter ridge twice as wide to make it look a little more balanced
3) I used JSSBO (http://knitty.com/ISSUEfall09/FEATjssbo.php), which I think worked out really well; it lays flat, not too tight but not so loose that it looks off from the rest of the piece
