Here is a set of Salt and Pepper mills I just finished. Materials are bubinga and hard maple. This project is a rather easy one for those of you who haven't done it. I did one practice one to get the process and proportions right and then did this set. A couple of points to keep in mind when doing it are to use a good Forstner bit for the hollowing (Woodcraft sells a nice one by Bormax) and if you are going to do segmented use thick sides. You can see on these that the sides were almost turned away during the shaping leaving only a couple of teardrops rather then a nice flowing curve. This is because the bubinga sides were only 3/8 thick and the maple is about 5/8 thick. Reverse those thicknesses and I think you have a winning proportion for segemented peper mills.
I followed a tutorial by Adam Howard (oxhoward) posted on WWA. I think he won't mind if I post a link to it. He does great work.
