Now, you can attach your ribbon loops to the styrofoam wreath by simply poking the pins into the styrofoam, pushing them in all of the way. I found it was easier to work with one color of ribbon at a time so I could get them evenly spread out around the wreath. If you prefer you can completely fill in an area of the wreath as you go.
Once you get the hang of this, you can fill in the rest of your wreath...
