An archery target wherein a thermoplastic plastic film web is randomly gathered transversely and wound spirally into a disc-like formation with successive convolutions in engagement and combining to define interstitial openings or air pockets. The spiral convolutions may be kept from unwinding in a number of different ways including heat sealing of adjacent convolutions, covering the faces of the disc with an adhesively or heat sealingly secured cover sheet extending in gathered relation through the center of the disc and splayed outwardly onto the opposite faces, or backing one disc with another having oppositely wound convolutions and securing the abutting edges of the convolutions to each other or an intermediate sheet.
