Use multiple hooks to secure the garland, placing one on each end as well as several mid-points throughout the length of the garland. Floral wire is inexpensive and is usually green, which means it’ll blend in seamlessly with the garland. Make sure to use wire cutters to cut your floral wire to size, as you could easily damage your scissors if you tried to use them. Using the wire, tie loops around the garland branches and use those to hang the garland off the hooks on the wall. Nobody will ever notice and if the garland is artificial, once it’s time to take it down at the end of the season, leave the loops on for next year.
