"Mohair is unique among fibres in that is possesses a
beautiful halo of fuzziness that effectively welds the knitting together. Few and far between are the knitters who can pull back knitting mistakes in mohair with their sanity and sobriety intact. Those who choose to knit with mohair would do well to triple check that they have cast on the correct number of stitches, because errors are best abandoned. Also note that this yarn quality increases the chances of not noticing a mistake for 8 inches. This chance is upgraded to a vitual certainty if you have only the exact amount of mohair required for the project, or if you paid a crazy amount of money for it"
Frogging alpaca is not much fun, but surely better than mohair :)
Oh and I'm sure I'll be quoting profusely in the weeks to come as i work my way through the hilarious "At Knits's end - Meditations for Women who Knit Too Much" by Stephanie Pearl-McPhee gifted to me by the lovely Lindy.
