APACHE COIL BASKET bottom view

Pictured is the reverse (bottom view) of the Apache coil basket that I recently posted. Using a stereo microscope I have been able to determine that the coils are formed on a base of 4 or 5 thin reeds The wrap reeds are then tightly coiled around the center reeds. When the wrap reed ends it is cut off and a new wrap is begun. It is almost impossible to see where the wrap reeds sart and end. They appear to be just one long wrap. Using a microscope I can see the ends . All the reeds seem to be the same thickness. The black may be dyed or some other type of wood.
Reeds do not appear to be grass but wood.
I presume that it is done while the reeds are wet. The construction is very dense and stiff. I have been advised to never pick it up by the edge but use 2 hands and pick it up from the sides.
The construction is so dense that I have always picked it up by the sides. It is so dense and tight that it appears that it could hold water.
