Sometimes you get really interesting effects with distinctive pieces of wood, like this black knot in a piece of Obeche. Look at how the lines of black spray out from the centre creating a very unusual effect.
The variations in each piece of wood – even of the same type – is one of the things I find really appealing about wood because each board ends up with it’s own particular quirks.
As for the nose lay-up using three different types of cedar , I think it’s looking good. The joins are nice and tight and they all line up with each other on the centre line, which is about as much as one can wish for really.
