We started with a printable place card kit from a craft store. The cards are already perforated, there is a slight crease at the fold line, and there's an embossed square around the edge. I found a stamp that resembled the flower on the invite, and a peach chalk-based ink. After a few test runs, we were in business.
We found it was best to stamp the cards before printing them. With the chalk-based ink, we found you had to be careful in handling it or you get chalk residue on your hands.
