Feather or Swallow

Tossing up between two shawls at the moment. I'll be able to finish the cardigan today (not counting blocking and buying and sewing on buttons), but right now I'm itching to cast on for a shawl.

Trust me though, I've started binding off the body of the cardigan, and have 25 rows of ribbing to go. I'll finish the thing today.

Then:

Japanese Feather and Fan Shawl (IzzyKnits) in a winter blue silk/linen ColourMart yarn. Or,

Swallowtail Shawl (Evelyn A. Clark) in a light gray Cashmere/Merino/Nylon/Viscose ColourMart yarn.

I've swatched in the gray, but if I decide on the silk, I'll have to do a swatch for that. The ColourMart yarns are oiled for machine knitting, and require some serious washing before you see the end result. They recommend doing this with the finished object, but since I've never used this yarn before I want to know what washing will do to it.

I sneakily printed both patterns at work, and I guess it all comes down to what I feel like in a few hours when I've weaved in the ends for the cardigan.
