Try a beading punch in place of a single point. A single point can sometimes get stuck in it's little mark in the background and soon it becomes a crater. The beading punch is much easier to keep moving and will do a better job of flattening the bottom of the background. Try a variety of sizes. I am using a very small punch.
You can also try a small punch with a flat face or ever so slightly rounded like what you would use for sculpting. Let it dance on a diamond sharpening wheel to frost the face. Seems like the coarser the better.
