I'm making quick progress on my cabled sweater. The first 7" are knit on size 15 needles, and I thought that would be fun. No fun, however. Its like knitting with logs. After 7" the directions say switch to a size 13, which is much better. When I get to 16" I switch to size 11 needles. The needle size gets continually smaller as I approach the neck. This is knit in the round and its a really easy pattern to follow. The yarn is Knit Picks Sierra.
