I knit myself this little neck warmer a couple of years ago. It knits up with one skein of Green Label Aran weight yarn, has a really cute bobbly all over texture, and is the perfect way to display some precious pearly buttons (or whatever kind of buttons you fancy, they don't have to be pearly!)
What do you think? Should I write up the pattern? It's fairly simple and I just stumbled across my notes from when I knit it back in '09.
