Handy Tip
Here are suggested measurements for extending the curtain track or pole either side of the window. The curtain will occupy this space when stacked back. This will allow the maximum amount of light into the room. Divide this measurement in half for a pair of curtains or use as the total stack back space for a single curtain treatment.
