Have you checked out "Beyond Your Backdoor"? It's a nature store and a new division of Lesser Jewellers.
FireTape™ is made from a virtually indestructible two-ply prismatic high florescent plastic. FireTape™ has hook/loop (Velcro) on each end, sewn (not glued) on for strength. Strips can be chained together for larger trees or posts.
FireTape™ is removable, reusable and washable, season after season. Or just leave it outside - it is TOUGH stuff. FireTape™ is visible during daylight as well as brilliantly reflective at night or in low light. You need fewer FireTape™ strips per distance then common trail tape because of their great visibility.
