Well -- I'm a believer. Knitted socks for my brother's Birthday done in two days... no problem. Thanks to Thuja, the clever pattern designed by Bobby Ziegler who similarly needed socks for a family member and had mere days to get them done. Worsted Weight rocks for speed and they're pretty warm too. I ended up using Vintage Wool from Berroco and they're warm, cozy and have great stitch definition!
