That's right, steel symbolizes the 11th wedding anniversary. One more than 10, I chose the one rose in the shape of divinity with the strength of steel, to represent both the 10 years together, and auguring a solid future based in love. At Zazzle, you'll find this stunning rose design on several products to mark their special day! To the left, my unique 11th anniversary card exclusively at Zazzle, and on the right, by the makers of Art of Where, a chiffon scarf, that almost makes me wish I could do our 11th anniversary again just to get this scarf! Also, exclusively at Zazzle. :)
