I made these sunflower mosaic with variety of yellow and green stained glass scrap, and textured copper Van Gogh glass as a focal point. Each glass piece is hand cut and laid into a recycled copper metal coaster, grouted dark brown and sealed. Each coaster is a quarter of a sunflower that creates a lovely sunburst when put together. This elegant set of rustic mosaic coasters is made with 100% recycled materials.
