Hickory Headboard

This headboard is made of hickory wood which my hubby had cut down 13 years ago.
He went out in the woods and inspected the best trees, cut a few down and then let this hickory sit in our workshop until he had time to start building it. Right before we moved in he started on this project and had it completed in around 12 weeks. All by hand, it wasn't an easy project. We still lived in our trailer and our children were little when he got it in his mind to do this. He basically used a hammer and flat chisel to get down past 2 layers of bark. Then he sanded for what seemed like years. I kept on at him walking outside and quizzing him saying "How much longer"? After the sanding was done he brought it in our bedroom and bolted it to the bed frame - now this headboard is so heavy it took our son and him to carry it into the house and my hubby is a very strong man :) Only drawback is if we want to move it in the future, it would take an act of congress. After he got it set up in the bedroom, I put 3 coats of tung oil on it and then the added around 3 coats of polyurethane. We have leather which has to be cut in strips to wrap around the ends of the posts but haven't done this yet. I've seen this done but I should have paid better attention at the time because I cannot remember where to start the leather. If
you know anything about this or have any ideas, let me know. I'm supposed to cover those screw heads if I remember correctly. There's not many of them, only 2 on each end. Hubby asked me after this was done if I wanted him to make a foot board since we still had more hickory in the shop. I told him I wouldn't do that to him..... LOL
