Left over from a fine pea soup, carefully cleaned
and degreased. Each of the three white pieces
articulates with one of the browner pieces. The
surfaces are wonderfully complex.
I don't know what these metacarps are - mushrooms or vertebre or ?? but you have captured them very beautifully, Suzanne! They could be taken as flowers, too, when looking only at the thumbnail (violets :) ). Fascinating forms and patterns. Big vote!
