This is one of four I'm completing for Evelyn. We love multiple sketches per request at sketch-it. The artist gets to complete a series of sketches. Sometimes it's variations on a theme. One person in multiple locations or with different friends in each picture. Other times its different people from the same family.
We also like them because PayPal takes out less money per sketch because the flat transaction fee is spread out between more sketches. It's not going to make any of us rich but every little bit helps. Besides what we do here is about more than the money.
