Paint and/or draw
Where can I do this?
Are the costs to get started high or low?
Would I be doing this in a group, in a couple, or on my own?
Are there physical requirements that might make it difficult for me to participate?
Open to all. Possible to stand or sit.
So what's it all about?
Like creative writing, making art is a way to express your emotions, ideas, and imagination. It doesn't matter whether other people ever see it or like it. What matters is how it feels while you are doing it.
You can use anything you have to hand. Draw on a computer or the back of an envelope. Art supplies can get very pricey, but you can also get perfectly good paints and pencils at Dollar Stores.
If you want some instruction you can take a class. If you're feeling anxious and need encouragement to start, google "outsider art" or "art therapy" to learn more about people who produce art for themselves on their own terms.
