Using brewed or used coffee grounds in painting

Is it safe to paint on canvas with used coffee grounds.I had some saved in jar and they have molded. Is there a better way to keep them until ready to paint. Thank you

Honestly, I wouldn't use anything that has molded. If you want to include used coffee grounds, either use them right away and embed them COMPLETELY in some sort of acrylic or oil medium, or else make sure they are thoroughly dried out before using them. People do use them, but you have to be aware of the acid content they still contain and take steps to make sure they won't ruin your piece in the future by breaking down any papers you use. That's why I suggested embedding them in something that creates a barrier between them and the rest of your piece.

I’m not going to use the molded grounds.I guess I need to store in open container.I think they molded because they were in jar with a lid.I normally
Add modge podge or gel medium and paint to them to help it stick.

Good advice. My friend gave me a sunflower painting where she used coffee grounds as the centers surrounded by oils on canvas. I've had it about 20 years or longer.
