So I seem to have tumbled into the silk bin…
Planning on loosely following the Yvaine/textured shawl recipe, but alternating seed stitch, and lacey panels in the archangel to make it eligible for a last-minute entry to the socks and lace contest.

At about halfway I’ve got 18 rows stockinette in Tatami, 16 rows seed stitch in archangel, 16 rows st. stitch in tatami, 16 rows birdseye lace in archangel, 16 rows st stitch tatami, 16 rows garter, 16 rows st stitch..
I’m still not at all sure about the striping effect - these aren’t my colors, but they might look just fine on someone else…

Final Striping scheme:
Tatami Stockinette
Archangel Seed Stitch
Tatami Stockinette
Archangel Birdseye Lace
Tatami Stockinette
Archangel Garter
