Attach the seat of a chair to a tree stump for an impromptu sitting area. This is an especially good project if the chair has a broken leg. Remove the legs from the chair and settle it onto the tree stump. Mark the corners of the seat on the stump. This is where the chair should be secured to the stump with 3-inch deck screws.
Turn the tree stump into a planter. Hollow out the middle of the stump with a sturdy trowel or shovel and line the inside with chicken wire and sphagnum moss. Plant a larger fern or other decorative shrub in the tree stump. Alternatively, place a potted plant down inside the stump for a visual display that can be changed with the season.
Tuck bottles into the tree stump. Hammer large nails into various sections of the stump, spacing them out like branches. Slide colored glass bottles onto the nails for a decorative touch. Don't forget to put one or two on the top of the stump as well.
