This was an opportunity to break out my crimper, which hadn't seen action in years. I thought this was a fun treatment for the sentiment, too. I'm really enjoying the pen work, but I realize that the cards could also be cute without it. Today I used a sharpie, which gives a heavier line, but the border technique is pretty foolproof - you could get it to work with almost any pen and it would look great.
I especially like the little bee - I might have to make a bunch of those for my Rosh Hashanah cards.
