Last Christmas all my sock knitting friends received these. I couldn't resist and bought a kit for myself. All you need is a little left over sock yarn, size 000 double pointed needles and you're off. You can knit them in one sitting and you only have to knit one! They so fun and fast to make. Here's mine.
ps...hope everyone had a fun April Fool's Day. I know I did. My husband graciously loaned me some creepy crawly things from his fishing box. I placed the best looking centipede on the drivers seat of my daughter's car at lunch time and a lizard on the steering column. She said she screamed when she opened the door. She told me that she doesn't think I'm very funny. :)
