new to the KAL

I've just joined this KAL and have been trying to decide which laceweight from my stash I'll use for this shawl. It's probably between Zephyr in Suede or Zephyr in Cassis, and I'll be going up a needle size or two since I have plenty of both these colors and would like to make the shawl a bit larger. I'm a fairly tight knitter. I'm impressed with all the photos I've seen so far of everyone's progress. The Sage Zephyr is lovely - a favorite color of mine. :)
