I have recently been re-painting a few rooms in my house, and I have many colors of indoor house paint left over. I have a small house, and every room is painted at least one color (except my kitchen which is painted white). I decided to use these paints for my May 12 x 12 x 12 piece. Seeing that I've been painting the rooms with acrylic based paints, and that fabric paint is also acrylic based, I thought I'd give it a try. I'll post my May 12 x 12 x 12 piece, and comments about using house paint vs fabric paint, as soon as it's finished. Hopefully in a few days.
