Is it a dumb idea to try to paint over those mass-produced canvasses that are everywhere now? Some of them come in decent wood floater frames which I imagine could be covered with tape before gessoing and painting. I picked up a free one from Facebook marketplace and want to experiment with it. It’s 30x40 inches and had a few dings and depressions which I got out with an iron and steam on the backside. Should it be primed with something like Kilz first and then a few coats of gesso? I know this isn’t archival and it’s nothing I would ever try to sell but … it was free! I’m slowly recovering from hand surgery and can’t even tie my shoes yet but someday I’d like to see what I can do with this. Thanks for any thoughts.
