polyurethane techniques

When I polyurethaned my cabinet, it looked horrible. It was all bumpy and stuff. When we sanded it down between coats, it looked as if we took every off. So we stopped sanding it for the third coat. It looked pretty bumpy. The directions on the back of the min-wax polyurethanes are pretty...
