My idea? Design something that would be lovely to receive, compliment many different style sensibilities and (most importantly) be reasonable.
My answer is a small silver watchface with a ruffle-edge black ribbon band. It arrives gift-wrapped in my signature clear bag with hot pink tissue & ribbons.
For $22 (plus $3 s/h), this could be the answer to your teacher/hairdresser/babysitter gift list. Available on my blog only - see sidebar.
It's a delightful gift...right on time.
