According to tradition, you'll have to wait 15 years to give glass to your spouse as an anniversary gift, but a glass is a perfect present for bridesmaids even before the wedding. Etch a set of tumblers with the bridesmaids' names and a decorative motif, such as a ring of leaves. You can take them to a professional, or etch them yourself with etching solution sold at craft stores. To make the presentation even more special, buy a flat of pansies at your local nursery, and set one in each glass, to be transplanted after the wedding.
