Harry,
We never get around to doing our own projects, so you are not alone. I know nothing about designing closets but it seems to me that if you go to your own closet and take some measurements for hanging height, rod depth, count the numbers of shoes (here's a tip it should always work out to a even number). Also make a seperate section for all the leather goods. I would assume it might be a good idea to have some cedar in there somewhere. Maybe even a good opportunity to have a locked or hidden drawer.
