Abstract
A synthetic microfiber blanket having a uniform thickness is formed from a nonuniform blanket having thin or feathered lateral edges. The nonuniform blanket is cut transversely into a plurality of discrete pieces of blanket of uniform length. The plurality of discrete pieces of blanket are arranged with the thin lateral edges in overlapping relationship to form a blanket of a desired width and thickness. The overlapped, discrete pieces of blanket are then joined into an integral blanket of uniform width and thickness by entangling together fibers of adjacent pieces of blanket. A scrim backing can be incorporated into the blanket for added strength and dimensional stability.
