Running a single carved design across two drawer fronts sounds like a decorative choice. It is really a sequencing problem, and it forces the whole piece to be built in a particular order.
The two drawer fronts have to be made first, fitted to their openings, and then held together as though they were one board - clamped in place, in the carcass, exactly where they will finally sit. Only then can the motif be drawn across them and cut. Carve the two fronts separately on a bench and the halves will never meet: the oval will step, the sprays will not line up, and the eye catches a misalignment of half a millimetre instantly on a curve.
The bombe shape makes it harder again. Both fronts are curved, so the carver is working across a surface that falls away in two directions, and the line has to stay true as it crosses the gap between the drawers where there is nothing to rest a hand on.
Then everything is taken apart. The drawers come out, are finished individually, and go back - and from that point on they are not interchangeable. Swap them left to right and the pattern breaks.
It is why our artisans mark each front on its underside before the fronts are ever separated.
