HL has some whispy looking yarns that would knit up similar, though they wouldn't have mohair in it. Look for those that are labeled 6, for super bulky/chunky, or have a label gauge of 11sts/14 rows = 4 in. (10 cm) on size 11 (8mm) needles. Other yarns to look at would be RH Symphony or Lion Jiffy. They're not as expensive as the Romance yarn.
