What's an unusual hobby anyone can get into for very cheap?

1. Woodburning! You can get a starter pen with a variety of tips for $15. Poplar is cheap and easy to burn on. Try it out, homies.

3. This one requires a sewing machine, but revamping thrift store clothes. If you don't have a sewing machine, then just thrifting. You never know what cool clothes you can find, or what you can sew out of them.

4. Dorodango is one that I never see in these threads, granted it's not particularly exciting. It's making [shiny balls of dirt.](http://thelaststraw.org/wp-content/uploads/2015/09/4.jpg) I've considered trying it but haven't yet. Basically you make a ball of mud, sprinkle dry powdery dirt on it, let it dry, then wet it again and add more layers by repeating that. Then at the end you rub it with a soft cloth to polish it a bit. Because you use fine powdery dirt it's able to get very smooth and shiny. I've heard that in Japan it's only done by very young children as an activity (I'd guess the equivalent of finger painting, not sure though) so I imagine it isn't very difficult to get decent results, and if you've got dirt and water near you it's free. I think a sieve of some sort is useful for powdering the fine dirt, and I've also heard of people using plastic bags to speed up the drying stages, but even if you buy that stuff it's still incredibly cheap as far as hobbies go. You could also probably buy dirt to use if you don't have much variety, I've seen red dorodango from areas with red soil for instance. For additional variety, I'm not sure if it'd be feasible to selectively polish certain areas to try to make patterns of shiny and matte dirt, or maybe mix colors of dirt, or dye/stain the dirt somehow. It's something that I want to experiment with eventually and see how much can be done to produce different effects.

6. Cross stitching! Buy a small design kit to get started and learn how to stitch, and then you can buy your own materials and create designs after the fact for cheap (considering the time invested in each project).
