I pivoted towards canvas panels bc yeah: I noticed people bought artwork on the panels as often as they buy my works on paper.
Stretched canvas take up A LOT of space, both in my room and at markets. A lot of these markets, you only get 6 foot tables. It's the same with wood panels of 1/2" or more.
But having a sturdy canvas to paint on is great...
I like are these new aluminum panels that you can paint on. I only have a few bc I'm figuring them out.
