I'm an amateur spinner. It's great fun!
There's a thread kicking around here on how to make your own drop spindle from a CD and a dowel.
There's also a fabulous website, probably the closest site to KH that exists (thankfully it's on another topic!), with a ton of great videos on how to spin! www.joyofhandspinning.com Enjoy!
That alpaca yarn sounds yummy!
