Ok, fine: ceramics.
I used to go when I lived in Warsaw and there was a pay-monthly-and-stay-as-long-as-you-want. Now I've moved and all the ceramics places charge per hour, which, apart from being expensive, is much less fun.
I hear there's a group of grumpy old women doing ceramics nearby. I want to infiltrate said group and learn from them.
