I did something like that last year (I took a week off from work to take a weaving class). It was the best holiday I could have given myself

I was interested in learning to weave and this gave me the opportunity to find out whether I would enjoy it (before spending all the money on equipment). But I also met some really great people and had a great time.

Take the class, it is only 10 days of your life but you may regret it later if you don't.
