Give your Christmas decorations an atomic-style photo. Display one or more of these fringed onion decorations on a credenza or mantel, or hang them in a window.
Draw a large mid-century-inspired shape (1 to 2 feet) on a large piece of cardboard or foam core. If you're having trouble drawing the shape freehand, look online for a template or pattern.
Use a utility knife to cut out the shape from the cardboard. Be sure to put something under the cardboard before cutting to avoid damaging the table or work surface below.
Flip the ornament shape over so that the good side is facing down. Trace the shape onto the other piece of cardboard. Then cut it with a knife. You should now have two matching trim shapes.
To make the sides of the topper, use a ruler to draw long rectangular strips about 3 inches wide. Depending on how large your ornament and cardboard are, you may need to cut several strips to make the sides.
To assemble the pieces, turn one of the trim pieces over so that the back is facing up. Use masking tape to attach the strips to the ornament. Apply the tape to both the inside and outside of the trim. Follow the curves as best you can.
You may want an extra set of hands for this step. One person can tape while the other holds the strip flush with the trim. It may take several strips to create the sides, but don't worry; The strips will not be visible when the embellishment is made.
Use more masking tape to place the second trim piece on top of what has already been assembled.
Use fringe scissors to cut fringe on a streamer roll. Leave 1/4" to 1/2" from the top of the cutter uncut.
Apply a drop of glue to the bottom of the ornament and one to the top of the fringed streamer. Lay the wire over the trim's glue strip and press down firmly. Continue the layer until you have made a complete turn. Cut off the excess. Start again with another strip of fringe about 1/2" from the previous one.
About halfway through the trim, change to a different color or metallic stripe. Then continue wrapping the fringe in the original color until you have completely covered it. And you're ready!
