The soft draping and folds of Roman shades add color and texture to your windows, enlivening your decor. You can sew your own flat roman shades in just the fabric and color you want, following these guidelines.

Step 1: Purchase and Install the Wood Batten

Choose an inside or outside window mount for the shade, and buy the correct sized batten. Affix the adhesive-backed loop strip to the front edge of the batten. Attach the batten to the inside top frame of the window, or to the wall above the window frame as desired.

Step 2: Measure the Fabric Length for the Shades

Make the shade length from the top of the wood batten to the length you want it to reach. Add a 2-inch hem at the top and a 4-inch hem allowance at the bottom. For patterned fabric, allow extra material to match the pattern vertically.

Step 3: Calculate the Width of the Shades

Make the finished shade 1/2 inch narrower than the wood batten. Add 1 inch of seam allowance to each side.

Step 4: Hem the Shade

Press and sew 1-inch hems down the sides of the shade. Press and sew a hem 2 inches deep at the top. Sew the hook strip to the back of the top hem, hook side outward, to attach the shade to the batten.

Step 5: Bottom Pocket

Fold up a 1-inch hem allowance and a 3-inch wide pocket at the bottom of the shade. Cut the 1-inch dowel to 1 inch narrower than the shade and insert it into the pocket. Sew the pocket closed at both ends.

Step 6: Make the Dowel Pockets

On the back of the shade, measure evenly spaced sections, from 8 to 12 inches wide, down the length of the shade. Cut and sew a length of twill tape across each with 1/4-inch seam allowances. Insert the 1/4 inch dowels, cut to 1 inch shorter than the width of the shade, and sew the dowel pockets closed.

Step 7: Add Twill Tape Ring Strips

Sew on 3 columns of twill tape ring strips down the back of the shade, from the top to the edge of the bottom pocket. Two will be set 2 inches in from the shade edges, with the third set midway between them. Ensure each ring rests on a 1/4-inch dowel.

Step 8: Attach the Cords

Cut 3 strands of cord each the length of the shade plus its width. Knot one cord to each of the bottom rings, and thread it straight up through its ring column to the top. Run the strings through the eyelet cords on the batten, pull to one side, fasten acorn pulls and wrap around cord cleat, well above the floor.
