My favourite to spin is Alpaca. I to,will spin anything and any blend. I have spun my own dogs (hair and even won the novice section of the show with it that year). My dog is a german shepherd border collie cross and has the softest finest under coat. Its lovely to spin.I have spun camel,angora, dog, cat,mohair silk,Alpaca,wool, soy silk ,cotton and blends of all different things. I would like to spin corn(inego),milk thistle, quivit and cashmere. I am going to see if there are any unusual fibers at the Fibre Fest in Brisbane in a fortnight. Its the biggest fibre festival in the state so there is a good chance to pick up something i haven't tried yet.
