I needed to do this because it was a toss-up between a blackwood pull and a cocobolo pull. Both might work equally well but I'm concerned of the amount of contrast between the pulls and the beech, should I have very contrasting colors or more of a subtle contrast. Having said this, I'm leaning towards the blackwood at the moment. A light tan background with a black pull works aesthetically in my opinion.
In the photo I have prepared a rectangular pull and am shaping the back square. This particular pull is rectangular, but I have the other option of a more sculpted, rounded pull. I'm not sure at this point, so I'll begin with this. I could have mocked up a small block of wood and darkened it black to be able to do this testing, but not too much more work is actually involved in making the blackwood pull, so I decided to do this instead. You can see the large block of blackwood in the background from which I have resawn and cut the small blank.
