To my eye, the symmetry of the black lines conflict with the non concentric pattern of the effect created by the wedges. The symmetrical lines work way better in the piece with concentric circles (in the four lines piece shown). Perhaps an interesting effect would be to change the black lines into lines created by the same woods but opposite colors as they intersect! This might add some contiuarity as opposed to the “in your face” effect of the Wenge. This challenging glue up will help fill those long cold winter days in Sweden nicely Lennart!!! BTW, congratulations on your excellent alignment of this glue up; I know what I propose to you would be an undaunting challenge for sure!!
