Cut three lengths of wide satin ribbon diagonally to form equal-sided diamonds. Pinch each diamond at the center, and pin to hold it. Hold all three together, staggering them to form the six-leafed blossom, then fix together by looping 26-gauge wire twisted at the back; using wire cutters, remove excess wire at the twist. Cut the stems from four store-bought stamens and attach them to the front of blossom with craft glue.
Use green ribbon, about half as wide as the first, for the decorative leaves. Cut two lengths about three times as long as they are wide. With the back side up, fold half the ribbon over so it forms an L shape. Fold the other half of the L over the first so it covers the previous fold. Cinch the bottom of the resulting house shape and hold it with a pin.
Shave the edges off of a 19-inch Styrofoam wreath form to give it a rounded profile. Wrap the form with satin ribbon, securing the loose ends with straight pins. Affix ribbon poinsettias and leaves to the wreath with large straight pins (which will be hidden within the folds) held firm with subtly applied hot glue.
