I've had this lace for years in my "treasure" box of notions I've inherited from sewers gone by. I used it in the waistband of Belle's Easter dress, so it is fun to put it in her hair as well when she wears that dress. You can buy lace like this at a fabric store.
Draw the bangs back and use a bobby pin to hold them in place. Put the lace on the top of the head covering the bobby pin. Tie it in a bow at the back of the head under all the hair.
Add some bobby pins to the the lace like in the picture. Mine are glittery ones from Gimme Clips. Try to cross over the hidden one underneath to keep it sturdier.
