A method of continuously producing a flexible drywall joint filler having a central spline portion adapted for cooperation with a joint defined between a pair of adjacent sidewall panels and a pair of substantially thin edge portions, comprises extruding at a predetermined extrusion rate a continuous strip of flexible material having a predetermined width, pulling the extruded pre-formed strip of flexible material at a pulling rate greater than the extrusion rate thereby completely forming the thin edge portions on the strip and reducing the predetermined width by about 30-65% to a completed width, and cooling the material at the completed width to form a continuous strip of flexible drywall joint filler having "feathered" edge portions.
