I have created these panels to be used with Photoshop in conjunction with the Bulkmockup Plugin application, you can purchase it here:-
 
BULK MOCKUP PLUGIN
 
The panel generator offers a variety of sizes for printing, for example if you sell fabric you could make matching panels to go with main and coordinating fabrics with a click of a button... no more tedius drag and dropping in each design.
