Wine Cork Coasters: Start with a square cork coaster from a craft store. Then look for corks that are near the same size, and cut each in half lengthwise with the knife (a band saw will work for more experienced crafters). Arrange in any pattern you want, as long as they fit on the coaster. Excess coaster can be trimmed once the corks dry.Put a liberal drop of glaze or glue on the flat side of each cork, and press to secure on the coaster. Repeat until space is covered.
