Preserving Fall Leaves - Keeping the Color ~ Soak leaves in 1 part glycerin to 2 parts water for one full day; lay out to dry. **UPDATE: Tried this, did *not* work. Leaves do stay flexible but are somewhat sticky & deteriorated after a while. Have not found ANY method that truly preserves their color if they're exposed to any light at all. #DIY
waxed leaves... Make sure your leaves are completely dry. Melt some beeswax in a double-boiler. You can use new wax or old candle stubs (optional - add a few drops of cinnamon oil). When the wax is thoroughly melted, take the leaves by the stem and immerse them, one at a time, in the wax. Hold them over the pot to drip a bit, then lay them on waxed paper to dry.
