8 inch diameter loaded goatskin head for the Dholak. Loading may or may not be completed. If the load is not applied- simply spread an even layer approximately 1/4 inch (6mm) in thickness on the INSIDE of the head. Restrict the load to the center area of the head and spread it to about a 3-4 inch diameter (75-100mm diameter). You may also choose to use 100% silicon.
