Silk and linen are the traditional materials for the 12th anniversary. For a romantic twist on this material, try the silk roses to the left! We also really like the personalized anniversary throw and pillowcases.
Both silk and linen lend themselves well to luxurious clothing gifts of robes, shawls, shirts, skirts, dresses, and lingerie.
Practical gifts like fresh, high-thread count bed linen, tablecloths, towels, cushions, and other home decor would be appropriate too.
If you would like to give jewelry, then opt for pearl which is the alternate modern material.
