Thanks, guys, for all the comments. What I like most about the bowl, is the sheer simplicity. A single, sweeping curve, no beads, coves, foot or rolled rim, just a simple curve. It makes it a very simple shape to produce - so much so that I'm now using up loads of offcuts and making replicas of it in all sorts of sizes. I've discovered that the shape works equally well with contorted grain patterns, as it does with straight grain, as the shape in the bowl causes all sorts of pleasant curves in the grain.
Here's a smaller one in amazaque/ovangkol, it's out of a 6x3 blank and is just under 3mm thick - finished with carnauba over melamine
...for such a straight-grained piece of timber, you've got to love those curves!
C&C always welcome....Les
