Well I am a knitting fiend on my first sock. I chose to use 100% mercerized cotton, because I wanted to see how the construction would come out (I just did not understand how it is done). I am liking it very much. Although I think I picked up a couple more stitches on the gusset, but I think for the most part it will be okay. Will let you know how it turned out. UPDATE....Completed my first sock on 05/18/09 (had to figure out the kitchener stich). Now I am casting on for the 2nd one. Picture to come soon of the complete sock. YIPPEEEEE so excited.
