Someone ( they occasionally read this blog) I love is in desperate need of a new hat. Being allergic to wool, I found some silk/bamboo yarn. The problem arose of how to make it warm. So I jumped onto ravelry.com, knittinghelp.com and YouTube. Seems like double knit is the answer, so here we go. I'll keep you posted.
Trying out posting from my phone. Let me know how you think it's working.
