Can you please list some hobbies?

Hobbies that don't involve electronics (video games, TV, phone etc...) and that I can do at home. They also have to be done by yourself, or with your animals. They also have to be free. No going to the store to get wood to whittle or stamps to collect.

So far I have:
Reading
Cooking
Update: I meant like you wouldn't have to go to the store for something special. Sewing costs money too. You have to buy all the stuff to sew with.
