Start by holding your length of vine and wrapping a couple of circles to use as your size guide/ base.
From this start wrapping the vine around this base. Every time you come to the end of the vine length, just tuck the end of a new piece into a loop on the wreath. Just keep wrapping until the desired thickness is achieved.
Just like that and easy enough to do that you can make one while you prune! Isn't homemade satisfying : )
