I'm very excited that I had a customer return for a second purchase the other day. I have been thinking about ways to thank customers for repeated business, even my friends! One was to make something small, like a pin, and drop it in the box. I decided to go with a gift certificate instead. It can be given to a friend or family member and I have written the Esty member name on the back to be referenced for discount.
I hope this will be adequate in expressing my appreciation.
