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.
For example, you have a 60 inch table and want a 15 inch drop (halfway to the floor), you multiply 15 by 2 (15x2=30) then add the table diameter (30+60=90) to get 90 inches, which means you need a 90 inch round tablecloth.
