A couple of weeks ago I aquired some Moda Vera Envy [see my review here] for $1 per 50g skein at Spotlight. I eventually cast on for a beanie. It knitted up very quickly on 6mm needles [US 10]. So much so, that I have been knitting a beanie a day for several days. Every one of them is different. DD now calls me the "Beanie Factory'. Ten beanies down, six to go [then all the yarn is gone]!
