Art can be done with almost any medium.
I make miniatures from all kinds of found items.
Lots of free sewing tutorials online and I’ve cut apart old clothes to use the fabric. Buttons and zippers can be scavenged that way also.
You can make iron on stencils for painting graphic tees, from paper and grocery bags. I have a tutorial on here for that.

It tends to crack faster with washing and wearing but that can be a desired aesthetic, too.
There’s a YouTube channel called five minute crafts, I think. Lots of ideas there, as well!
