NonnaAnnie said "you have reminded me that I used to keep my knitting wool in the freezer, it stopped it shedding fibres that get up you nose and in your eyes while you are knitting, particularly with mohair type wool."
Gosh that takes me back! I remember that advice too, but I think the last time I knitted mohair was for cardigans for my DDs way back when they were about 3 and 5... So over 30 years ago! Eeek! Where did the time go? I got the mohair in El Kilo (now Abakhan) where you could buy remnants of fabric by weight, and fibre cheap too. Mostly the fabric was cut into 2 yard lengths, so useless for curtains in our Edwardian terraced house. Very occasionally you could get lucky and find longer lengths, still have some in my stash, though we've moved to a semi since then, so don't need the length any more.
Perhaps time to Freecycle to someone who needs the long lengths now.
Sorry, went rather off topic there!
