I have been ordering some online, peach baskets from a barrel company, dog hats from a doggy store, etc.

Props seem to double the sales potential. One sale for a classic portrait and a bunch of smaller sales for cute props. I have also started using more formal props for seasonal props and breed specific props. Breed Specific?-shotgun scene with a birddog, Jim Poor's idea of scottish kilt with Scottish Terrier, country scene props with a bloodhound, etc.
