A few years back I helped do an activity where we made fresh Christmas wreaths. Wreaths sell for around $20-$25 at the grocery store or at a tree farm and they are super easy to make. When we did this activity we bought the wreath frames in bulk from someone who had a wholesale card for items like that. The cost for us was about $3 a wreath frame. To make a wreath you will need
Wreath frame (they are metal)
green wire (the same type of wire you would need to make a corsage)
wire cutters
garden pruners
tree boughs/branches
decorations-bows, pine cones, berries etc.
I got all of my branches when we picked up our Christmas tree. Usually Home Depot or Lowes will have a pile of excess tree branches and if you ask they will most likely give it to you for free because they will be throwing it out.
