I will consider commissions, or if you would like to buy a koi pond painting, please send email to firstname.lastname@example.org. These are painted on masonite board with a varnish. I just nail them to the floor. Safe to walk on and wipe off with a wet cloth. (these are about 24" x 36" or larger).
Koi ponds start at $300 each. (Also on Etsy.)
