Get a simple hair clip. These could be silver or painted in any other colour that you want. Clips that clasp shut are the most popular ones for flowery embellishment. These clips are easily available in jewellry shops and even drug stores and are usually an inch long. However, you can also use any other clip as long as it has a surface for attaching the flower. Plain clips are better so that the flower stands out on its own.
Purchase a Hawaiian flower from a craft store. The flower type, colour and size is totally up to you. These flowers are used in not only jewellry but also in craft and decoration projects. Get a fabric flower for yourself.
Get a fabric glue along with the flower. Cut off any stem or base that the flower has so that it is totally flat to be glued. Apply glue on the surface of the clip. press the flower on it and apply pressure for some time. Let the glue dry for five to six hours. You can keep constant pressure by placing a book on the clip.
Check the flower if it is secure to the clip or not. Once assured that it is, clip it on your hair and you are ready to shine. Make more of these clips, in different colours so that you can match with your dresses and can also give off as gifts.
