I made a bunch of flowers at one point last year, intending to use them in headbands. Considering the giant plastic bag of them in the yarn basket, I never got beyond the first step.
The good news is that I had a ton of coordinating ones on hand when I decided to make barrettes.
The actual barrette (space for hair) is 2 inches, while the edge-to-edge measurements of the flower part is 4 inches long by 2.5 inches wide and measures about half an inch thick. There are two blue flowers side-by-side with the purple flower on top. I attached the flowers by wrapping purple embroidery floss around the flat edge of the barrette and sewing the flowers on with it.
