Use a long running stitch down one edge of the long strip of ribbon.
When you reach the end, leave the needle in place and begin pulling the thread slowly gathering the ribbon.
Starting at one end, begin to roll your ribbon into the center of your flower. As you add each layer, the ribbon will be a little more relaxed.
Place one of your two 12" strips of ribbon two inches from one edge of your fabric. If you are using satin ribbon, pin only at the ends ~ pin marks will show. Sew both sides.
Add your second 12" strip overlapping the first one (again two inches from the edge of the fabric). Sew in place.
Sew your flower onto the fabric.
Now you can decide how you want to use your finished project!
