On many natural projects, the object will stay looking better if you give it a coat of sealant. Some of the products used for this are finger nail polish, and clear acrylic spray. The sealant most often used in this book is Thompson's Water Seal. It is made for wood fences and decks (available in home improvement centers), but will work with most wood based products. It can be applied with a brush, cloth, or the object can simply be dipped into it. The first coat takes about 24 hours to cure. Then a second coat can be added. Cleanup is with mineral spirits. You may find a 4"x4" cloth easiest to use. The same cloth can be used repeatedly. By applying hand lotion to your hands before using Thompson's Water Seal, you can usually wash up with soap and hot water.
One other use for Thompson's Water Seal is to waterproof paper. Just one coat does the trick. Use it on a sample to see if the ink will run.
