Question on leather stacked handles

[Lucky777Leather]

Ok guys be gentle I'm a rookie to the wonderful world of knife making. I have a question about making a stacked leather knife handle. This will be the first time I am making this type of handle. Seems relatively self-explanatory. Can someone explain the steps for me on how to do this. I plan on using some spacers in some small metal washers in it to add a different type of look. When I go to sand and shape that handle what grit sandpaper should I use? What do you use to coat the handle once you are complete? Does anybody know of a step-by-step type of guide to help learn this process. Any help would be greatly appreciated.
