A blanket that may include a layer of material with trapezoidally shaped notches in two opposite sides of the material. An upper panel of the material may be configured to wrap around a user's upper legs with the user in a sitting position, and a lower panel of the material may be configured to wrap around the user's lower legs. Fasteners removably attach right and left edges of the lower panel together. A method of covering a portion of a user's body with a blanket may include placing the blanket on the user with an upper panel of the blanket over the user's upper legs, and a lower panel of the blanket over the user's lower legs, wrapping left and right edges of the lower panel around the user's lower legs, thereby surrounding the user's lower legs with the lower panel.
