Last fall, when I was just getting back into knitting and wasn't very fast at it, I made neck scarves for my whole family. They went very fast, so fast that I had 11 extra that I wrapped up in clear celophane and ribbons, so people could see the colors, and got our local beauty shop to give them out to their elderly customers who could use an extra bit of warmth.
I used one skein of homespun yarn for each scarf and cast on 12 stitches with yarn from the center pull strand and the outside strand, so I was knitting with a double strand of yarn from the same skein on size US 19 needles. Boy did they go fast!
Knit every row (garter stitch) and just keep going 'til the skein is used up. The scarf will be just the right length and the homespun is incredibly warm. Beautiful, too. So they should bring some bucks!
Best of luck and thank you all for caring so much for one of God's challenged children.
