These magnets were made by using the flat glass vase fillers like you find at Hobby Lobby, Wal-Mart or in my case, The Dollar Tree. Cut circles to fit using scrapbook paper. Write letters using a sharpie or find letter stickers. Then glue the round papers to the flat side of the glass pieces using E600 glue. Next, hot glue a magnet to the back. Easy, Cute, Cheap!!
