How to Interline Draperies

Updated February 21, 2017

Interlining your draperies is an easy way to give your drapes a more professional look and add insulation. Interlining means sewing a layer of fabric or batting (usually cotton or wool) to the back side of your drapes. This gives the curtains a more finished appearance and the interlining can insulate a room against drafts and sunlight. Interlining also protects your drapery fabric from fading and makes the drapes more durable. By interlining your own drapes, you can save hundreds of dollars over purchasing custom made draperies.

Lay the drapery panel face down on a flat surface. Using the seam ripper, carefully remove the seams on both sides and the bottom of the curtain. Be sure to leave the top seam intact. Measure the length and width of the curtain.

Lay the interlining fabric on a flat surface. Measure out a piece of fabric the same size as the measurements taken from the curtain. Cut out the fabric and lay the liner on top of the facedown drapery panel.

Carefully fold both the edge of the drapery and the liner over the back of the drapery to recreate the original seam. Use the straight pins to hold the fabric in place. Repeat this on both sides and the bottom of the curtain. At the top of the drapery, pin the lining fabric along the seam just below the rod pocket or tabs.

Using the sewing machine, sew along both sides and the bottom of the drapery to close the seams. At the top seam, carefully sew along the original seam to attach the lining to the drapery. Remove all straight pins and repeat steps one through four for each draper panel.
