We made a warm window curtain from a faded, old queen-size comforter, leftover fabric and clearance curtain panel for $1.50. My daughter needed to cover patio doors facing the north for the winter. On the Great Plains, the wind blows at a good clip out of the south in summer and out of the north in winter, with few obstacles to slow it down.
Both sides of the comforter were covered with a red fabric panel on each side of the red and gold damask curtain panel and gold striped, denim weight fabric as a band across the top. The fabrics were purchased from the 'bargain' tables for $1-$3 a yard in coordinating colors. I attached the fabric to each side of the comforter by top-stitching around the top, sides, then the bottom. Extra length allows draping on the floor like a draft-stopper.
The rod casing is 12 wide tabs sewn to the back so it sits higher to cover the window. It worked better than I hoped and the cost was $3 for the panels since we recycled fabrics from other projects. We doubled up the light weight summer curtains on the other window.
