How to Make Warm Window Curtains


Warm window curtains help to hold the heat in your home during the cold winter months. They keep drafts out by blocking them with their thick insulating lining. Lined curtains are basically like any other curtain or drape, the difference being the insulating fabric lining the inside of the curtain. Choose a printed or colorful fabric for the outside of the curtain. Purchase the same amount of insulated fabric for the lining.

Things You'll Need

  • Tape measure
  • Fabric
  • Yardstick
  • Fabric marking pen
  • Fabric scissors
  • Insulating fabric
  • Straight pins
  • Sewing machine
  • Matching colored thread
  • Curtain rod
  • Use a tape measure to find the width of the window. Multiply the width measurement by 2, and plan to make two curtain panels for the window, and the lining, at this measurement. Find the height of the window using the tape measure. Add at least 6 inches onto the measurement of the height to ensure the edge of the curtains will fall below the edge of the window. Add more length onto the measurement for longer curtains. Plan to make both curtain panels, and the lining, at this length.

  • Lay the curtain fabric face down on a large work surface. Use a yardstick to measure the fabric according to your width and height measurements. Mark the fabric using a fabric marking pen by running the pen along the edge of the yardstick, using it as a straight edge. Cut the fabric to size using fabric cutting scissors.

  • Lay the insulating fabric face down on the work surface. Use the yardstick and fabric marking pen to measure and mark the fabric according to the same width and height measurements you used for the curtain fabric. Use fabric cutting scissors to cut the lining to size.

  • Lay the curtain fabric face down on your work surface, making sure it is straight and has no wrinkles in it. Lay the insulating fabric directly on top of the curtain fabric, keeping the edges straight with the edges of the curtain fabric.

  • Fold the top and bottom edges of both fabrics over ½ inch. Pin using straight pins. Push the pins down through the fabric then back up through ½ inch over from where the pin was inserted, putting a pin in every 3 inches. Do this for the right and left side, then do all four sides of the second curtain panel.

  • Stitch all pinned edges of both panels using a sewing machine and a color of thread that matches or blends in with the fabric used for the outside of the curtain, not the lining. Stitch twice for added strength and durability. Remove all pins when you are finished stitching both panels.

  • Fold the top edge of each curtain panel down 3 inches. Pin the edge of the fabric to the two layers of fabric below it, ½ inch in from the edge, or 2 ½ inches down from the fold. Do this to make a curtain rod pocket. Stitch each panel along the pins, stitching twice for extra strength. Remove all pins, slip a rod through the pocket, then hang the warm curtains as you would any other type of curtain. Pull the curtains closed when you want to keep heat in and drafts out; keep them open to let in natural sunlight.

Tips & Warnings

  • Make sure your fabric scissors are sharp, as dull ones will fray the edges of the fabric and will make cutting difficult.
  • Use care and caution while using sharp scissors and a sewing machine.
