Mesh ribbon is incredibly easy to use and attach to your mechanics by using zip ties (a.k.a., cable ties).  You can use pipe cleaners (as an alternative) instead of the zip ties, but zip ties secure the ribbon tightly at each puff or bunch, which makes the pulling and tucking more efficient as you work to create your design for a wreath or swag.

The zip ties also work well for attaching ornaments because they slide easily into the ornament hooks.  The size you want to get is at least a 3-4″ length for the zip ties, or you can go longer, and just cut the tail ends off at the end of your project.

Zip ties will last for years, where I think pipe cleaners can wear a bit over time.  And if you want to take apart your project later (for whatever reason), zip ties are easily cut…
