Leave the shade down to keep a room cool, or flip it up and attach the loops to hooks you've screwed into the sides of the window frame. You'll let in light and reveal a pretty contrasting color, no cords needed.
Measure the width and length of the window. Add approximately 2" to allow for hemming at the top. For bottom and sides add 1/2."
Wash and dry the linen to preshrink it before sewing. Iron out all creases and wrinkles.
Cut the linen to size.
Fold over the raw side edge of the linen by 1/4" to the wrong side and press with an iron. Fold over again by a further 1/4" and press again. Pin, then stitch the hem down. Repeat for the other side seam and the bottom.
To make the curtain rod pocket, fold over the top edge of the linen to the wrong side by 1/2" and press with an iron. Fold over again by a further 1 1/2" and press again. Pin, then stitch the hem down.
Cut two 3" pieces of twill tape. Double one piece of twill tape and, using a needle and thread, secure it onto the bottom corner of raw side of the panel with a few stitches. Repeat using the remaining twill tape on the opposite bottom corner.
Slip the curtain rod through the pocket. Fit the rod in the top of window frame.
Screw cup hooks into window frame, a little less than halfway up. Slip curtain loops onto cup hooks to raise the shade and reveal the contrasting color.
