There are several miscellaneous pieces that make family-style meals just a touch nicer.
Instead of using that dirty, decades-old potholder under your hot dishes, opt for decorative trivets.
Rather than serving directly from the saucepan, use attractive serving dishes. I love white dishes, since they coordinate with almost anything, and make the food look amazing!
Salt & Pepper
I recommend having a set of salt and pepper shakers/grinders specifically for use at the table. The kitchen set can be your backup, but may be greasy and unpleasant for guests to handle.
