Take a ribbon of your choice of color, pattern, ect. And cut it to your desired length.

Take the strip and make it into a circle. You can either glue the ends together of sew it.

Line the glued or sown ends to what ever the center is. Pinch the top to the bottom to create a bow shape.

Sew or glue the center down. Or, if your feeling lazy, just take another, smaller, thinner piece of ribbon and wrap it around the center. Then glue or sew it.

Take a hair or bobby pin and put it through the ribbon on the back of the bow.

Now you ready to rock a super sick hair bow all your own!
You can also put cute little buttons or toy pieces on the front by gluing it.
