This is my second drawing of the rose using latex house paint and a little acrylic paint. I was really unhappy with it initially and began to add more and more layers and eventually using a rubber stamp with house paint to add some texture and additional interest. It is done on 22" x 30" watercolor paper.
I love working with the house paint and have found that brands other than Benjamin Moore work very well. B Moore paints have raised their prices to be very, very expensive compared to other paints. I was lucky to find at my local hardware store some little sample bottles. I have no idea what they were for originally and I had the feeling the store's staff thought it a little weird that I was going to paint pictures with it. I recommend giving it a try with some left-over paint.
