I have the canvas for painting, I just need a 4'x4' lightweight but sturdy frame built. I'll have extra canvas left over, if you build an additional mini-frame, I'll make you painting! Here's an instruction video: https://www.youtube.com/watch?v=H5tApIe58GE
I do mid-century modern-style abstract patterns. If I get good and start selling them, maybe I can pay for additional frames from you on a regular basis.
