Hi guys! I'm going to start doing yoga and other exercises in my room which has hardwood floors. (Allegedly. There's a lot of squalor I'm going to have to deal with in here). I would like to buy a mat on which to do these exercises, but I don't know what to look for in a mat. (I do know what to look for in a Matt: tall, skinny, dark-haired and scruffy, like my big brother's skater friend who I had a crush on when I was 13.)

Anyway, do you have a favorite brand? Is there an inexpensive option so I don't feel too bad about wasting money when I inevitably quit? How thick should my mat be? Is it okay if it doesn't have a dragonfly design on it? Do I have to wear yoga pants?

Thank you for your help!
