Some old favorites and some new designs . . . do you have a favorite?

Darcy and I have been getting ready to participate in a couple of art/craft shows this summer. Also we have put our tiles in a couple of local stores (KC Custom Framing and Fabrics and Dehn's Gift Shop) and they have been selling well. KC is going to put some on their website, so we will have a place to send people who are interested - progress! We have had lots of interest from other stores in the region and we are finally getting our act together to make it happen. We love to make the stuff, but are not that good at the business end, designing line cards, etc. We are trying to choose from this set which 4 or 5 tiles (we narrowed it from over 25) to focus our marketing around. Do you have any favorites?
