Welcome to KH!
row 1: cast on one stitch (you can use the thumb loop method here if you want), (K1, p1, k1) all into the next stitch, turn as you would at the end of a row.
row 2: p3, turn
row 3: p3tog.
These sound like directions for a small bobble. What is it the pattern you're making? Can you give us a pattern link?
