Now would be a good time to get yourself a drum head and plenty of rope (80 to 100 feet, 1/4" diameter) to tune with later. If you make your drum head from animal skin you'll have to keep the skin lubricated and covered, kept away from sunlight to lengthen the life of the drum head. I decided for my application that was more trouble than I really wanted. So I opted instead for a synthetic drum head. I'd recommend searching Amazon.com. If you go this route, keep in mind a 13 inch drum head (as in my case) refers to a 13 inch drum shell.
In the mean time, do any staining or varnishing you want to your drum!
