I have been making then with long bias cut strips of organza folded for years. I like the snap for attachment. I have backed the flower with a piece of matching felt then glued on a jewerly pin backing. It can be placed wherever you want this way.
You can add folds of green for leaves on the back or the velvet purchased ones.

I have used this for a Christmas ornament. I wove red and green in 1/8" wide ribbons. Two colors in 10 yards of each makes the length necessary. Then glue it around a styrofoam ball in lines to circle the ball completely. When dry, glue a gold cord in between the circled rows. Add a loop of ribbon then a gold balled pin to hold it at the top and another pin at bottom for a finished touch.
Makes wonderful hostess gifts if you want to invest the time for a GOOD friend.
