Some crafts that use large pine cones are pine cone wreaths, decorative pine cone trees and pine cone ornaments. To make a pine cone wreath, hot glue pine cones in clusters to a grapevine wreath base so that there is no space between the pine cones, let the glue dry, paint the pine cones a complementary color to the home's decor then paint glue and dust glitter onto the cones once the paint dries.
To make a decorative pine cone tree, secure a large Styrofoam craft cone to a base such as a large planter. Get 2-inch flower picks, wire the cones to the picks and stick the picks in a downward diagonal motion into the foam. Use larger cones at the bottom, working to smaller cones toward the top. Tuck sheet moss into any spaces between the cones so that the Styrofoam can't be seen.
To make pine cone ornaments, cut one 1/4-yard and one 3/4-yard velvet ribbon per pine cone. Hot glue the 3/4-yard ribbon to the flat base of the pine cone, and allow it to dry. Tie the 1/4-yard ribbon into a bow. Hot glue it to the base of the pine cone where the first ribbon is glued. The base of the cone now becomes the top of the ornament. Tie it to the tree or a chandelier with the long ribbon.
