Using a double ended tunisian crochet hook (my favorites are from the River John needle company), the pattern is simple, with a light, yet warm result. Experiment with different types of bulky yarns and light, airy complementing yarns.
I used the whole skein of buly yarn and a little over half the ball of kildsilk haze.

Chain 110 with bulky yarn, join in the round, taking care not to twist the chain. (do not break yard)
work in sections of 25 - 50 stitsches: Through the back “bump” of the chain, dc with the kildsilk haze, leaving the stitches on the tunisian hook.
Close the stitches up to the last 3 stitches each time with the bulky yarn, to the end of the first round.

Continue in the round using the tunisian extended simple stitch (kildsilk haze for the dc part and the bulky to close the stitches) until the piece is as big as you want it. Cast off with the bulky yarn on the last row.
