Here's a post with a bunch of cards made with American Crafts Hazelwood collection from the folks at 1canoe2. All cards are A2 sized (4-1/4 x 5-1/2 inches) in size.
A few of these cards incorporate fun gold-tone shaped paper clips. Flat clips on cards are easy to slip into envelopes, and can be protected from postal sorters with a corrugated (or other type of) insert in the envelope.
These were fun and fast to create and I really don't want to put it away...but the Valentine papers are calling...
