Sarah who is now back working at the shop on weekends (yeah!!!) just finished this sweater - Leyfi from Interweave Fall 2010 issue. She knit this sweater with 2 balls of Eco + in a fantastic green colourway.
You need to see it, but it won't be at the shop forever, she will take it back once it starts getting colder, which BTW, I think will be soon. So, if you want a quick to knit sweater, this is a good option.
