I send a thank you card with each order.Sometimes for my cards I just use plain paper and sometimes I use gift wrap,the plain side,its cheaper,and sometimes I buy plain cards at a dollar store and cut them in half.Make sure you use plain designed cards for this.Anyway I get feedback and repeat customers.A few have said I loved the little hand written note in their feedback.But you need to leave feed back for your customers to.I just say,thank you for your purchase from my shop is very appreciated,and its a true note.Hope this helps.
