Salle à manger et cuisine

A runner is the most useful single piece, since it frames the table without covering it. Placemats and napkins build from there. A full tartan cloth is a strong commitment and works best at Christmas, Burns Night and Hogmanay rather than year round.

Yes, because the sett is woven through the cloth rather than printed on the surface, so it cannot crack or lift the way a printed cloth does. Wash warm rather than boiling, skip the bleach entirely, and hang or dry flat.

Consider the room rather than the family. A large dark sett dominates a small dining room. Muted and weathered colourways sit against wood and neutral walls easily. If you want the family tartan and it is bright, put it in a runner rather than across the whole table.

Yes, and it is a detail people notice. Order the table pieces at the same time as any clothing in the same sett, since tartan woven in different batches can vary very slightly in shade and that shows under table lighting more than it does in daylight.

Only if you want it to, and at a Burns supper or a Hogmanay dinner it is a detail guests notice. Order the table pieces and any clothing in the same sett together, since batches vary slightly in shade under artificial light.

A runner and napkins is usually enough. Once placemats, coasters, a cloth and napkins all carry the same sett, the table reads as a themed restaurant rather than a home. Let the runner do the work and keep the rest plain.
