There's this place in Vienna called "
MadeByYou" where you can pick some pottery, decorate it yourself by making use of the large selection of paint, paintbrushes and templates, and after glazing and burning it it's yours. They have everything ranging from mugs and plates to figurines, and the prices are OK too, considering that all materials are included, as well as the two additional aforementioned processing steps.
The atmosphere is really pleasant, and it's full of kids who are obviously just as excited about the whole idea as I am. The staff is very friendly and helpful too. For Vienna UT ("TU Wien") students there's even more good news - MadeByYou is about 5 minutes away from the uni, vis à vis of Centimeter.
Oh, and this is what I made:

I probably still need some practice. :P
