My third class was a Knitting Ergonomics class. I would highly recommend this class for all knitters. We should all be aware of how our body responds to the task of knitting. Having gone through the start of Carpel Tunnel Syndrome and Ulnar nerve problems from computing, I know I don't want to go through the same problems with knitting. So, keep an eye out for this class and take it! Protect your ability to knit.
Would I take classes again? Most definately. I took one class a day, which gave me time to peruse the market.
