Each year, we watch the number of Christmas cards we receive dwindle a bit. We're guilty of falling short on this task, and are worried that letter-writing is quickly becoming a lost art. So in order to bring it back, last night, we sent emails to friends asking for their most current addresses in hopes to revamp a beautiful holiday tradition. While there's an inherent carbon footprint to card-sending, we think it's an important way to let friends and family know we're thinking of them. So here are a few ways to lessen the impact. Jump below for our ideas and then share your own. • Think recycled, or plantable, or local. There are plenty of recycled holiday cards on the market now--we even noticed some plantable ones at Target the other day. Your local art museum or book shops will likely sell handmade paper goods from folks in your area. • Opt for a refillable fountain pen rather than a disposable one. Not only does it look classy, but a refillable pen saves a lot of disposable plastic ones from ending up in a landfill. • Make your own cards. Do a simple block print (here are instructions at ReadyMade) onto recycled paper cards. These pop-up cards from Martha Stewart would be a great project to take on, and you could likely find Earth-friendly paper at a craft store. • Buy stamps that show your support for a great cause. You can purchase these custom Earth-touting stamps at Zazzle, or opt for the Scenic American Landscapes collection through the USPS (the current collection depicts 13 Mile Woods, New Hampshire, which is dedicated to sustainable logging and conservation). • While it's less old-fashioned (and pretty much defeats the purpose of this whole post) but has a very small impact... you can always send a holiday email!
