Sympathy & Thank You Cards: Counterfeit Kit Challenge

When putting together my July Counterfeit Kit, I made a card kit add-on because I knew I was going to make some cards for a card swap. I chose to feature the Michael Strong Whirl-a-gig collection from Club Scrap, but only used the blues, whites and yellows in my main kit. So, I put the coral papers in my card kit add-on, along with some other papers, flowers, ribbons and buttons:

I like to keep Sympathy cards fairly simple, and I like the ones I made. I hope the coral isn't too cheery/bright for the sentiment. What do you think?

I also made some thank-you cards, which I think worked just fine with the color palette (although the light coral/pink paper doesn't scan very well). It's been a while since I participated in a card swap. For this one, I'm sending in four thank-you cards and getting four different thank-you cards back. Same thing with the four sympathy cards.  I used to participate in them all the time but got burnt out on them.
What about you? Do you do card swaps?
