What Does Simmer Mean? Simmer is technically the heat that is just below the boiling point of the liquid. A simmer is reached within a pot on the stove when the liquid is hot and just has a bubble or two forming at a time and reaching the top of the liquid before popping.
Decide how much overhang you want from your tablecloth. For most purposes, an overhang or drop length of at least 6 inches (15cm) is appropriate. A shorter drop length may make the tablecloth look too small for the table.
Calculate the length and width of your tablecloth. Multiply your desired drop length by two, since the tablecloth will hang from both ends of the table. Add this result to your table's length to get your tablecloth's ideal length, and to your table's width to get your tablecloth's ideal width.
