Place lined seat frame face down on fabric. Trace three inches out from edge of cushion around entire frame using temporary fabric pen. Cut along line. Tip: If using a patterned fabric, appropriately position the design on the seat cushion.
Attach fabric to frame using staple gun. Begin by stapling fabric to frame at the center point of each side, and then at each corner, pulling fabric tautly around frame.
After sides and corners are stapled in place, continue securing fabric to frame by working from center point to each corner. Pull fabric snuggly around curved corners to eliminate tucks on top side of cushion.
After seat cushion is covered with new fabric, reattach to chair frame using original hardware.
