I made a scarf recently for a project called Knit Your Bit. It's sponsored by the World War II Museum in New Orleans. I had seen it advertised at a yarn expo and they were asking for donations. I thought this was a good cause, and I had some extra yarn, so I thought I'd make one. I chose a pattern from their website, but any scarf pattern would do. I added a short note of thanks that I hope went along with the scarf to the veteran in need. A few weeks later I got a nice letter of thanks from the WWII Museum.
