The wing bones can make turkey calls. The heavier leg and thigh bones, depending on size, can be used for decorations, as in a boned necklace, or the handle for a small patch knife, or for a powder measure, as suggested. You will want to protect those fragile bones with several coatings of either an epoxy, or polyethelene, or a good stock finish with driers in it. If you just let them dry out, they becomes to brittle, and will crack or split at the first bump. Remember that bird bones are hollow, and carry the blood supply. Deer leg bones are often used for handles and measures because they are much thicker, are not hollow, and have a heavier grain structure. But even they need to be protected from drying out and cracking.
