Here are the items you'll need:
Start by removing the garland from the Dollar Store wreath. Note, you could also use a Styrofoam ring.
Next you'll make the paper roses, simply cut the cards into a circles and then cut each circle into a swirl. It helps to cut the swirl skinnier on the outer rings.
Once all your swirls have been cut, start rolling your roses. Begin at the outer edge of the swirl and work your way in.
Glue your roses together with the glue gun and then affix to the wreath frame.
Here is the final wreath. Looks great and very economical. Put it anywhere (but not likely outside).
