Duvet cover or comforter (I bought this light-weight comforter at Target over four years ago)
Ribbon, cut to the length and width (plus a few inches) of your duvet cover or comforter
Ultrahold HeatnBond, slightly thinner than the width of your ribbon
Iron and ironing board
Before starting, be sure to pre-wash, dry, and iron your duvet cover or comforter.
Next, one of the most important steps of this entire project is to measure the length and width your duvet cover or comforter. I’d do it twice just to be sure. This determines how much ribbon and HeatnBond you need.
One you have your measurements, add a few inches. One, because you’ll be folding under the ends of the ribbon for a finished look. And two, because the duvet cover or comforter might stretch out a little while ironing on the ribbon.
Go back to the starting end of the ribbon. There will be a loop where you folded under the end of the ribbon. Cut a small piece of the HeatnBond, remove the paper backing, and slide the tiny piece of adhesive into the loop. Lighly press and hold the iron on that section for 2 seconds.
With the adhesive-side of the ribbon down on the comforter or duvet cover, press and hold the iron for 8 to 10 seconds on each section of the ribbon until the entire length of the ribbon is bonded to the duvet cover or comforter. Be sure to start with the looped end of the ribbon.
