I completed my summer scarf. I cast on 350 sts with Nashua Handknits Ecological Cotton on a US 10 needle and knit in garter stitch through 2 skeins. Not rocket science I know, but it makes a perfectly good summer accessory.
I also cast on for the Ravelympics Hana Jason's Gathered Pullover from Winter 2007 Interweave Knits using Garnstudio Alpaca. This knits up so fast - it's sport weight knit on a US 7 needle.
