Mylar tinsel is difficult to find except when winter decorations are in stores. During this time larger chain drugstores, craft, party planning & discount department stores and even hardware stores may carry Mylar tinsel. For the rest of the year a suggestion would be to purchase sheets of Mylar found at craft stores. These sheets of Mylar can be found in the gift wrap and gift basket supply isle. You can use a paper cutter or paper shredder to cut the sheets into strips like tinsel. Hunting/fishing shops sometimes carry mylar tinsel as a fishing lure.
