So what do you do if you want a wax seal for a prop document, but don't have all the accoutrements at hand? Liz Gubernatis provides a possible answer with this tutorial on using buttons to make expedient seals. I'm inordinately amused that an article designed for high-achieving brides is applicable to making props.
"The flatter your button, the easier it is to get a good imprint in the wax. Rounded buttons will work, but may require more wax or a finessed impression technique to see the whole image. Raid your local button jar, garage sales, or thrift shops for buttons with fabulous imagery, or if you're looking for something specific, try local yarn and quilt shops for a wide selection of awesome finds."
