My largest pieces I made my own canvases for I made and stretched a 3foot by 3foot canvas for an oil painting. I've actually only sold one piece and it was to a family member who wouldn't just take it. So they gave me 50USD so I could buy more supplies. I want to sell more of my art but I don't know where to start. I move fairly often so I can't have my pieces sitting in a consignment studio.
My fiance bought me a dozen tiny 2inch canvasses for my birthday so I could make tiny paintings. That might help me with pixel art too! XD
