The anchor was seen as a symbol of strength as anchors hold down ships even in the stormiest of weather. It was also a popular symbol because of its close resemblance to the cross. Anchors were also used to mark safe houses for those seeking refuge from persecution.
While sheet sizes vary by brand and style, a fitted sheet is similar to its respective mattress in measurements; for instance, 78 inches wide and 80 inches long for a king mattress, compared to 72 inches wide, 84 inches long for a California king. The fitted sheet has a little extra width in the king-sized set.
Professional sheet pans used in commercial kitchens typically are made of aluminum, with a 1 in (2.5 cm) raised lip around the edge, and in the United States come in standard sizes. The full-size sheet pan is 26 by 18 in (66 by 46 cm), which is too large for most home ovens. A two thirds sheet pan (also referred to as a three quarter size sheet pan) is 21 by 15 in (53 by 38 cm). A half sheet pan is 18 by 13 in (46 by 33 cm); quarter sheets are 9 by 13 in (23 by 33 cm). The half sheet is approximately the same size as mass-market baking sheets found in supermarkets, and the quarter sheet is a common size for rectangular, single-layer cakes.
