I had a customer a couple of weeks ago order a pair of my Embroidered Silk Earrings as a Four Year Anniversary gift. I had never thought of that, and loved the idea. Frank and I have looked at the traditional Anniversary gift lists before, but never knew what to give for paper, cotton, etc. Silk is the modern gift for a four year anniversary. Here is a list of traditional and modern gifts for each year.
I would be thrilled to work with you on a custom piece of Silk jewelry for a Four Year anniversary gift. I think giving an heirloom piece of art jewelry with great significance is a wonderful gift idea, if I do say so myself. I can also create custom jewelry designs with other materials such as paper, cotton, wood, etc.
