Measure desired length for the flat part of the decoration. Add 30 1/2 inches for the pleated half-moon plus 1 1/2 inches for hanging. This is half the length of bunting required for the decoration.

Cut 2 identical pieces of bunting: Begin cutting after a star and end right before one, so you'll have about 3 inches of blue on each end. Trim off hems for easier pleating.

Join the 2 pieces together side by side (make sure stars line up): Overlap by 1/2 inch, and adhere using fusible webbing; iron to fuse. If you prefer, stitch the 1/2-inch overlap together. The final width should be about 32 inches.

Mark fabric 30 1/2 inches from the bottom edge with disappearing-ink pen.

Pleat the half-moon: Starting at the bottom edge, make 1 1/2-inch accordion folds (A); iron after each fold. Continue up length of fabric, stopping at the mark you made. The raw edge of the fabric should point down.

Stitch along the center of the pleated rectangle to create a pivot point (B). Make one more fold, and crease with iron.

Attach rectangular dowel in the crease with fusible webbing; iron, fabric side up.

Sew channel at top of swag (for hanging): Fold fabric over 1 1/2 inches, and stitch 1 inch from top edge. Insert round dowel.

Connect the half-moon: Fan out sides of the pleated rectangle, and adhere with fusible webbing (C); iron. Or adhere sides with tape for easy disassembly and storage.

Screw eye hooks into ends of the round dowel. Hang over a window.
