I have casted on for the Tricorder Hat. I found the pattern on Ravelry. I have come across a new term (TK2) that I am not familiar with. And, after looking at the notes I am even more confused. I do not understand if I slip the sts off the needle where to put them. It is not a dec row. Maybe it’s late and I am overtired, but this has completely thrown me for a loop. Here is the pattern http://www.ravelry.com/patterns/library/tricorder-hat
TK2= slip one st and k next st. Without slipping st from needle, K the slipped st. Slip both sts of needle.
