Here’s a couple of sweet designs from Ecoluxe paper goods.. Ecoluxe uses paper selected specifically for their eco-friendly features. They have FSC Certified recycled papers and envelopes and 100% tree-free paper, made from 100% recovered cotton fibers or bamboo. They also print double-sided which sometimes reduces the need for extra cards. You can get a small sample pack for $5.00 off their website.
