A button for attachement to a sheet (14) of compliant material that includes a plastic body (42) and a cap (56) formed from malleable material secured to the body. The flange (44) of the plastic body has an integral thin ring (48) to which the outer portion (58) of the cap is wrapped around and secured. Heat causes expansion of the plastic body; but, because the ring (48) is thin there is little expansion and the periphery of the cap is not cammed open to become loose on the body of the button. |
