Weaving the interlacement pattern into the back of the drum became quite a complicated task. I finish each drum by creating a pattern using the same number of thongs that fasten the hide to the cedar ring--for this new drum the number is 11. Although I was able to make the pattern from a single length of thong, which is important because an interlacement is continuous so the eye travels its complexity without a pause, the resulting spaces were too narrow. The addition of a five sided rawhide rope to pull open the shape unexpectedly created another whole level of interconnection.
In fact, the resulting pattern is so complex that I have been unable to wrap the thongs with leather hitching which is my usual way of finishing the back fastening of my drums. And yet when I looked closely though the window-like opening in the center, I felt I was looking though to the sky with the clouds parting to show its face of eternal blue. This airy web is just right.
