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.
Most mattresses come in standard sizes -- twin, full, queen and king -- with twin being the smallest and king being the largest. So planning a bed linen purchase necessitates knowing the dimensions of the linens made for standard-size mattresses, such as flat sheets, so you can buy those that fit. A twin fleet sheet measures roughly 70-by-100 inches, give or take a few inches. A full-size flat sheet measures roughly 85-by-100 inches. A queen-size flat sheet measures roughly 90-by-106 inches, and a king-size flat sheet measures around 108-by-106 inches.
