Great eye. I messed up a little here. I skived the edges of the yellow middle layers at a very sharp angle, and didn't use enough glue. So, they were splitting a little after stitching. Then I filled that with some extra glue hoping they would stick now, but they didn't.
Next time, I will pay more attention to the skiving angle. I am struggling to sharpen my French style 12mm skiver. Once I figure it out, I guess I will practice some more.
