Leaving a long tail (about ½” [1.3 cm] for each stitch to be cast on), make a slipknot (this counts as the first stitch.) Place your thumb and index finger between the yarn ends so that the working yarn is around your index finger and the tail end is around your thumb. Secure the ends with your other fingers and hold your palm upward, making a V of yarn (Figure 1).
*Bring the needle in front of the thumb, under both strands around the thumb, down into the center of the thumb loop, then forward toward you. Now bring the needle over the strand going to the index finger to grab it (Figure 2).
Bring the needle back through the loop on the thumb, turning the thumb slightly to make room for the needle to pass through. (Figure 3)
Drop the loop off the thumb (Figure 4) and, placing the thumb back in the V configuration, tighten up the resulting stitch on the needle.
Repeat from * for the desired number of stitches. Distribute the stitches over your chosen needles and join for working in the round.
