So I saw these on the Weddingbee DIY gallery awhile ago, but I kept forgetting to post them. Having done the DIY-ish invite thing, it's really not so bad (minus the disaster of getting them cut at Staples.) We purchased our invite from Printable Press, but I seriously considered the gorgeous invites by Anna Skye over at Download And Print:
Another great resource are these free and very inexpensive ones from www.empapers.com as blogged about today on $2000 Wedding.
Are you DIYing your invites?
