A waterproof seal provides protection from moisture and liquids. You can avoid messy situations on clothing and furniture by making a waterproof seal, and lengthen the life of some craft projects by waterproofing joints and surfaces. A simple waterproof seal can be made from easy-to-find materials. According to Virginia Technical University, "adding linseed oil to the [beeswax] mixture makes [a] good waterproofing" solution. You can find all the necessary ingredients--beeswax, boiled linseed seed oil, and turpentine--at your local hardware store.
