Personally, I love it when a couple sends me a save the date magnet for their wedding; I can keep it on my fridge, think of them every time I go for some -ahem - vegetables, and somehow feeling more connected to their wedding. Terrill's Tiles has taken the idea of a save the date magnet and cranked it up a notch.
Using tumbled stone tiles, she hand-stamps and hand-paints each tile individually for a completely personalized look. And, she has a great range of styles - her Skull version would go perfectly with OffBeat Bride's Sacrificed free wedding website template, don't you think? Plus, the magnets on the back are strong enough to hold thick, card-stock invitations so guests can keep all of your wedding info in one (very streamlined looking) place.
