Flexible tacking strip (brand names Curve-Ease and Pli-Grip) finds it's specialty application anywhere curved surfaces are involved and visible tacks are undesirable. Two prongs are visible, these will grip the fabric as they are pressed toward the frame. The other tab has a hole punched in it through which a tack or one leg of a staple will pass, attaching it to the frame.
Align, mark and trim the panel. Push all the pronged tabs of the tacking strip about half closed so they are at about a 45-degree angle. Lay the OA panel over the area and pin or stay-tack in place so it will not move during marking.
Hook the fabric onto the toothed segments, pressing the fabric around with the fingers. A skewer is a handy helper to move the fabric around accurately. Keep the panel taunt during the tucking-under process.
