This isn't the video I used but I found it later and it's much much easier to follow if you want to make your own burlap wreath. I just used wire to position and affix the flowers to the bottom. It makes a world of difference in my little entry way.
Since I just used wire on the flowers I'm thinking I can switch them out during the different seasons and keep the same burlap wreath base. I'll let you know in the fall how that goes :)
