Shellac - sanding between coats?

Like Larry, I sand gently (with 400 grit) to get any nibs but, Charles is quite correct, the coats fully "burn in". I should qualify my sanding statement in that the coat after sanding with 400 is very thin, too thin to allow any ridges to build and thin enough to be nearly dry before I even finish. Almost like putting on a coat of wax. I'll also add that I sand after about 30 minutes without issue. This will vary with your climate.
