How To Make a Sequin Sash Belt
Guest Post by Kristina
The best fabrics for this project would be silk, crepe or satin. You'll want to use something that has a bit of structure to it, but not a fabric so bulky that you can't tie it in a bow.
My trim was an inch wide, so I cut the fabric strips two inches wide to give me a half-inch seam allowance on each side. The length will vary. You can use a length of cheap ribbon to determine how long you want your sash to be. I wanted enough length to make a pretty bow in the back, so I made it 55 inches long. I also used one strip of press-on interfacing to the inside for extra stability.
I attached the trim about two inches left of center. That way, the ties on the bow in the back would be even.
