1) I put in a row of eyelets that aligned with the arrowheads after clue 3 (just for fun really, while waiting for clue 4
2) I bound off using a picot cast-off, something I seem to have started to do with the majority of the shawls I knit. I guess I like a subtle scalloped edging... It doesn't seem overly whimsical or feminine here thanks to the arrow points. I love it.
For those interested, I followed clues BAABA (heh-heh, a sheepy "baaaah bah" it is!)
