How to Make a Roman Shade. Roman shades are a classic window treatment that you can make in just a few hours. Choose coordinating fabric to match your existing decor, and let the window frame your fabric by mounting the roman shade on the inside of the frame.
Making the Roman Shade
Measure the width and the height of the window. Measure the width of the window at different locations and use the measurement that is the smallest.
Purchase enough fabric and lining to cover your window. Add 1 3/4 inches to the width of your window and 4 3/4 inches to the length. Cut your purchased fabric to these dimensions.
Lay your roman shade face down and center the lining on the fabric. The fabric should be a 1/2 inch wider than the lining on both sides.
Place the right sides of your fabric and lining together, stitch the right and left side raw edges together using a 1/2 inch seam allowance and press both of the seams open.
Stitch the top edge of the roman shade together with a 1/2 inch seam allowance, and press the seam open.
Turn the fabric right side out. Turn up the bottom edge of the fabric 1/2 inch and hem in place.
Hem another seam at the bottom of the roman shade by turning up the bottom edge 2 inches and hemming along the previous seam.
Installing the Hardware, Lifting Mechanism and Mounting the Roman Shade
Mark horizontal lines with a fabric pen at equal intervals, 8 to 9 inches apart, on the back of your roman shade. The top interval needs to be 1 3/4 inches larger than the others, and the bottom interval will be slightly smaller than the middle ones.
Pin lengths of roman shade tube tape on each line, aligning the loop portion of the tape on the line and the channel portion towards the bottom of the roman shade. Sew the tape in place along the loop portion of the tape, being careful not to sew over any of the loops.
Thread three lengths of curtain cord through the loop tape at the center of the roman shade and down the length of the roman shade 1 1/2 inches in from each side. Tie the curtain cords in a knot around the bottom loop to secure the cord.
Insert plastic dowel rods cut 1/2 an inch shorter than the widths of the roman shade at each interval through the tube tape and one dowel rod through the 2-inch hem you stitched at the bottom of the roman shade. Fold the edges of the tube tape and stitch them closed; also stitch both sides of the bottom hem closed.
Cut the pine mounting board 1/4 inch shorter than the width of the top of your roman shade.
Attach a cord pulley on one side of the mounting board 1 1/2 inches in from the edge, and attach another cord pulley in the center of the mounting board. On the other side of the board, 1 1/2 inches in from the edge, attach a cord lock.
Tack the roman shade to the back of the mounting board with thumb tacks spaced 3 inches apart, across the length of the board.
String the cords attached to your roman shade up through the pulleys, and string all cords through the cord lock.
Cut three small holes in the fabric with a utility knife where you want to screw the mounting board in place, and screw the mounting board into the inside of the window frame.
Line up all your cords along one side of the roman shade and cut them at the length of the window frame. Thread the ends through a cord drop and knot the ends together. Pull the cord drop over the knot to conceal it.
