If you are expecting tears of joy during your ceremony you should carry a handkerchief down the aisle with you instead of a wad of toilet paper. It will photograph better and will be a nice keepsake. If you are sentimental you may want to ask for a hankie from your grandparents or have one embroidered for the occasion. If you use blue thread it could be your something blue. Most of the hankies on the sites below cost between $17 – $25.
Lil – Inspirations – Very pretty hankies, and an easy to use website.
The Lace Shop – Pretty hankies, but not many options.
