They are knit with Katia Mississippi 3 (cotton/acrylic yarn) on size 0 needles. The pattern is available on the Crystal Palace Yarn site and is called the Menehune Cobblestones. The pattern calls for Panda Cotton and I may knit another pair out of that yarn. Now I'll pick up the second of my Pomatomus socks and finish it. Then I can start several new socks (it's my incentive to finish the Pomatomus - they are such nice socks)!!
Here is my knitting fan. His name is Peppy and he often sits and watches me knit - sometimes likes to play with the yarn. He's 15.5 years old.
