I worked the first block of the Sock Yarn Blankie, using 2.5mm needles and some leftover sock yarn:
The turquoise at the bottom is the waste yarn for the provisional cast-on. The diamond, across the center, measures 3 inches. The block uses a very little amount of yarn. I thought I'd need a little ball about the size of a ping pong ball, but I think I could get 2 blocks, maybe more, from a ball that size.
I'd really love to have as many colors and as much variety in this afghan as possible, so I have a request. If you have any leftover sock yarn or fingering-weight yarn (variegated is preferred) that you no longer want, would you consider putting it in the mail to me? I've convinced some knitting friends to knit along with me, so any and all yarn will be shared and very much appreciated. If there is any remaining after we finish our afghans, it'll be donated for charity knitting projects. My email is on the sidebar at the right and if you write to me, I'll send you my mailing address. Thank you, thank you!
