How to Roll Up a Thermal Curtain With Sewing

Measure the length and width of your window and add about four to five inches to both measurements. Cut out all of your fabric and batting to that measurement. Cut out two panels of the regular fabric.

Lay one panel of the regular fabric down with the underside facing up. Lay the batting over the fabric and the heat reflective material over the batting. Set the final panel of regular fabric over the heat reflective material right side up.

Sew the layers of fabric together with a straight stitches running horizontally across the surface of the fabric. Space the stitches apart every three to four inches. Start the stitches at the top of the curtains and stop at the base of the curtains.

Slide the metal pole into the bottom most pocket on the curtains. Sew up around the perimeter of the curtains.

Pin the bias tape around the perimeter of the curtains to close off the raw edge of the fabrics. Sew the bias tape in place with a straight stitch.

Sew four to six buttonholes at the top of the curtains with the buttonhole foot. The curtain will hang on the hooks by the buttonholes. Alternatively, you can use grommets instead of buttonholes. Insert the grommets into the top of the curtains and snap them in place.

Cut out strips of Velcro that run the length of the window and sew them onto the underside of the curtains. Use epoxy glue to attach the other side of the Velcro to the side of the wall next to the curtains. This keeps cold air from leaking in when the curtains are closed.
