Hello Lucky! has always been a favorite stationery stop of mine. Their lovely cards have a vintage + handmade quality that are heightened by letterpress. Now they've rounded up a nice list of contributors for a new book: Handmade Hellos: Fresh Greeting Card Projects From First-Rate Crafters. Judging by the photos below I am sure it will be full of cute, creative ideas. If it is half as delightful as their store, it will be more than worth the minimal investment.
