Pine cones collected outdoors can bring mold, mildew or bugs into your home unless they are correctly prepared for indoor use. Learn how to prepare pine cones for crafts. No bleach. All-natural. (outdoor fall crafts for kids)
Place dry pine cones on a foil-covered baking sheet in a single layer. Bake in a pre-heated oven at 200 degrees for about minutes. Spray them with a little acrylic sealer to give them a little sheen and to give strength since pine cones are fragile.
