Take down and measure the existing curtains, if they are still hanging.
Measure the window, if the old curtains are not available.
Double the window width to determine the total width of fabric you need. Divide this figure in half if you are making 2 panels to cover the window. Add 3/4 inch to all sides to allow for the hem. Add 6 inches to the height measurement to allow for a 3-inch rod pocket.
Purchase lined upholstery fabric from your local fabric store. If upholstery fabric is too expensive, consider using shower curtains, table cloths or sheets for fabric. Often these items are inexpensive and can be cut to make several matching curtains.
Cut the fabric to the panel size determined in Section 1.
Sew a piece of plain white fabric to the backs of the fabric pieces if you cannot find lined fabric, Place the wrong sides of the liner fabric and the curtain together and pin them. Sew all sides of the liner fabric to the curtain fabric, leaving a 1/4-inch seam.
Place the fabric with the lined side facing up, measure and iron a 1/4-inch fold on all sides of the fabric.
Measure and iron another 1/4-inch fold to hide the edge of the fabric.
Sew the edge of the folded fabric to create the hem.
Place the fabric with the lined side facing up. Measure, fold and iron the top of the fabric down 3 inches to create the rod pocket.
Sew the edge of the folded fabric to secure the rod pocket.
Slide the curtain rod through the rod pockets of each panel. Place the curtain rod back into the holder, so the lined side of the panel faces out.
