Prepare binding strip by folding lengthwise wrong sides together and press. Open strips and press long edges towards the centre and press in place. Fold in half on original press mark, and press. Put aside.
Zigzag or serge 7.5” edges of exterior fabric and lining fabric. Place lining fabric and exterior fabric right sides together, mark 1.5” from each side on the top edge to mark an opening. Sew from each edge to the mark.
Press seam open. Top stitch around the opening. Place fabrics right side together once more. Sew the bottom edge to create a tube. Turn right side out.
Manipulate the mask so ½” of lining fabric shows above the opening, press. Sew around the mask with a narrow 1/8” seam. Lift the lining fabric at top of mask to insert twist tie or pipe cleaner. Sew on existing seam line to close.
Fold mask to create 3 horizontal pleats. Secure with clips and press. Sew along edges with 1/8” seam to secure pleats. (The aim is to make the mask height 3.5” to 4”)
For each side of mask, cut the binding strip 1” longer than the height of the mask. Open the strip and place right side of strip against lining fabric, aligning the raw edges, and folding the excess fabric strip to the front of the mask.
Flip mask over and sew on the binding fold closest to the edge of the mask.
Pull the binding strip away from the mask. Fold the edges of the binding strip in towards the mask, and refold the binding towards the mask, covering all the raw edges.
Slip the elastic into the folded binding. Clip in place and stitch close to the folded edge, avoid sewing the elastic. Repeat for other side of mask.
Knot or stitch the elastic into a loop on each side of mask. Pull on the elastic to allow it to slip into the binding. Your mask is ready to wear.
