I designed my cards so that they would interact well with frames; each animal image has two colored borders which make the cards appear to be subtly matted. So, if you're loving these cards, go pick out some perfect little frames for them (here, I've chosen some classic black wood 5"x7" frames)! Individually or in groupings, it really is a fun visual impact, and the combinations are endless. Personally, I can totally picture them in a stylish kids' room. Its' obvious I'm having some crazy fun with these cards...so of course I'm encouraging everyone around me to go a little pet crazy too. So, have fun with this idea! david hearn
