I did this project a few years ago and decided it would be a good idea to go ahead and post it online. I had an extra bass drum head lying around that I had no need for. I thought it would be neat idea to turn it into some sort of wall art. I finally decided to turn it into a giant wall clock. The hands are black and the black cent makes it hard to see, I plan to paint it white some day.

Step 1: Find an Appropriate Drum Head and Find the Center of Circle
My band teacher was throwing out old/unused drum heads, and I was able to obtain a 20-21" head for a bass drum.
After obtaining a drum head, the next you will have to do is find the center of it. I don't have any pictures showing how I did it, but here's a video that I think is excellent in showing how (minus the Macintosh voice over.)
Note: In the first step when you draw a line somewhere, I drew mine parallel with the Slingerland logo so I can make the clock lines parallel/perpendicular with the logo.
Also, I would not suggest using a sharpie on the head as it may not come off and it will show through, mine reluctantly came off with a Mr. Clean sponge. But I would stay on the safe side and use a non-permanent marker or a pencil.
