Choose a colour theme that looks appealing to you. If it is not a specific occasion and is just a family dinner on a Sunday, then you can play around with different colour ideas. The colour of the tablecloth should be different to the colour of the serviettes or napkins unless the napkin is placed on the plate.
If you are going to put a centrepiece in the middle of the table it then it should be the focal point of the dinner table. On many dinner tables, the food will be placed in the centre for everyone to serve themselves. If this is the type of setup you are planning on having then perhaps the centrepiece is for another day.
Centrepieces should not cover the face of the person opposite you. It either needs to be higher than the heads of the guests or only 20cm from the surface of the table. It could get uncomfortable for your guests to speak and not see the person’s face that they are speaking to.
Only have the necessary amount of plates and cutlery set on the table. Unless, the dish requires the person to use a specific utensil, rather have only one knife, one fork and one spoon.
Two glasses per person is enough for what they may drink for the evening. Usually a wine glass and a tumbler are placed for each person in case they want to drink juice as well as wine.
Decorative plastic under plates can be placed underneath the dinner plate to add to the décor colours. White plates are common as are white tablecloths so these decorative plates could bring a fresh colourful appearance to the dinner table.
