Today's card would be suitable for lots of occasions just by changing the sentiment. It's a super fast card, and would be another style easy to mass-produce if needed.
I began with a standard A2 sized card in Basic Black cardstock, and layered a piece of "Sweet Sorbet" DSP which measures 4" x 5-1/4". (free SAB choice)
The flower petals (Petite Petals) were stamped on a scrap of the "Sweet Sorbet" DSP using black StazOn ink. I used the matching punch to cut out the flowers. The flower stem came from "Fabulous Florets" stamped in Pear Pizzazz ink on a Whisper White layer measuring 4" x 3". The sentiment was stamped in StazOn ink also, and comes from the set called "A Dozen Thoughts." The white layer was attached to a Basic Black layer measuring 4-1/8" x 3-1/8" and adhered to the card front using dimensionals. Then I attached the flowers using dimensionals, and added pearls as the finishing touch. So easy! This style would be very easy to have made ahead, perhaps with just a "thinking of you" on the card front....then stamp the appropriate sentiment on the inside when you need to use it. (birthday, sympathy, get well, etc.)
If you wanted to leave off a sentiment entirely from the front, you could easily use a coordinating ribbon or baker's twine around the bottom in lieu of any wording. Either way, it would make a beautiful card and hopefully brighten someone's day.
