Using dye sublimation I am able to print my artwork onto hardboard coasters. This coaster features a print of my collage “Susan B Anthony Paper Mosaic,” with the slogan “Votes for Women”it measures 3.75 inches square and 1/8 inch thick, has a black edge, and a cork backing. Easy to clean, light weight, and durable these coasters are a great way to add artwork to a room.
