Form each piece of ribbon into a loop shape as shown in the picture. The ends should overlap about a 1/4" - 1/2". This does not have to be precise, just estimate each one. If your ribbon has a front and back side, make sure the front side is facing out. Poke a straight pin centered through the ribbon to hold the ends together. Start at the inside of the ribbon so the pointed end is on the outside of your ribbon loop.
Now I will show you how to attach the ribbon to the styrofoam wreath...
