My mom had recently purchased the Branch Out stamp set (currently dormant) but hadn't mounted it, so we decided that while I was visiting that week, we should ink it up and give the set a trial run. She had also purchased Fifth Avenue Floral (also unmounted) that I gave a whirl as well. Look for those cards in a day or two. My mom made a sample to put in the case with the stamps for reference and I made three cards with it. I like how the set allows such versatility. Playing with stamps I don't own is dangerous, though! I usually decide I want to add them to my wish list after ward! I'm still on the fence about this one, but I like the idea of using it for a gift card set or holiday cards.
Anyway, I made a "spring", "fall" and "holiday" card using that set plus Sincere Salutations (another one on my wish list--it's so long that I'm embarrassed to say how many sets are on it!) My mom didn't have any red ink and I didn't have any with me, so I think if I made the "fall" card over again, I'd put red in the leaves as well. The inside of that one says "Thanks Very Much" in old olive, in case you care. The others are blank inside.
