Teacher: Now, understand the problem? Solve this instance: [header] How to choose a tablecloth size [title] Consider the occasion. [step] If you're picking a tablecloth for an occasion, consider the nature of that occasion. Depending on the event type, there should be different levels of drop from the edge of the table to the bottom of the tablecloth. <sep> (A) In order to maintain your tablecloth size from a shallow angle, a tablecloth covering should be about the same size as the table. This means the tablecloth should start at a corner if it measures a foot in length, and extend to a further corner if there are more chairs. (B) [substeps] For a formal occasion, such as a wedding, you want a longer drop. Have about 15 inches from the edge of the table to the bottom of the tablecloth. (C) For the event size, choose colors such as gold, silver, and dark blue. For a more casual dinner where you'll only be using perishable food, try bright colors such as bright green, red, and pink. (D) If there is a necklace or other item from the event that's in your style, this should be found on the tablecloth. [substeps] If your dish will cost more money than the tablecloth you're picking, consider the nuances of the occasion while locating the tablecloth.
