Just day i finished my first pair of socks, and i totally understand the craze for sock knitting, it's portable, it's quick and there cozy. plus they are a quick and easy way to try out new stitch patterns.
the pattern i used is called Komet.
I found it as a free ravelry download, it's a brilliant pattern, i'm just glad i'm done so i can wear the finished results.
Knitting socks is a thing of my future from know on.
I used patons 100% cotton 4ply 100g and it took one ball to make a pair of size 5 komet socks with plenty to spare. The yarn is lovely to use but be careful it's a slippy yarn, i salvaged stitches many of times with these socks.
