Everyone has their opinions and preferences about quilting. It is my opinion that when someone in quilting says "you shouldn't, don't do, etc etc" ask them why and then make your own decision. I may not mind the bearding. Many believe poly batting is better for kids quilts as it washes better.
Such talk is what prevents our own creativity from coming out. Just remember these are opinions and not rules or laws. I just get "het" up when I read comments like this. (het was a word my grandmother used frequently - meaning my emotions get heated).
