Take two pipe cleaners and twist them together to make the base of the tiara.
Loop each pipe cleaner in half, stack the loops on top of each other and twist the ends together. Pull the individual petal out so that you end up with the following two sets
Squeeze the twisted ends flat with your pliers and lay them on top of each other positioning the petals so they alternate. Glue the two twisted sections together with your hot glue gun and snip the ends with your pliers.
Next glue each petal shape to the next about three fifths of the way up and continue doing this all the way round. This is important as it will hold the shape in place. Glue the twisted base pipe cleaners you did at the beginning underneath the petal arc. Bend the ends back on themselves
Finally, add your sparkly gem and use kirby grips to attach it to your hair.
