So here's my lacy scarf that I just finished blocking. If you want to make this scarf, you can find the stitch pattern in Volume 3 of Harmony Knitting Stitches. It's the "Spiral and Eyelet Panel."
This scarf was made out of just two skeins of Classic Elite's Montera yarn on size 9 needles. It measures 7" X 75" after blocking.
I have the old Harmony volumes but Interweave has now released them as three volumes: Knit & Purl, Lace & Eyelets, Cables & Arans.
