Sending Your Own Holiday Cards?

Sending a custom holiday card is a great way to show off your design skills while wishing your clients a happy holiday or new year. If you plan on spending money on mailers or advertising anyway, it's a great time to design something with a holiday theme and remind people you're open for business. If you're looking to spend less (or save paper), sending a well-designed email newsletter or email attachment can do the trick. Is anybody sending out custom cards this year? If so, please share!
