Chair sashes are strips of cloth, often of the decorative variety such as tulle, satin or organza, tied around the back of a chair in a bow. These sashes are placed for decoration and are often used in concert with a chair cover. In weddings, chair sashes are often used to dress up the chairs found in many rental facilities. They also help convey the colours of the wedding. Chair sashes are not difficult to make, especially when a fabric that doesn't need to be hemmed is used, namely, tulle.
Determine the width and length of the sash according to your personal preferences and the cost. A sash should be at least 2 inches wide and 3 feet long. Use a straight edge to draw a light dotted line along your desired dimensions with a fabric pencil.
Cut the fabric according your width and length preferences; if you are using ribbon, measure and cut the length.
Use a sewing machine to sew a small seam on all sides.
Add any trim you may want on the edges of the sash. Velvet ribbons look nice on most types of fabric.
Tie each sash to the back of a chair.
Consider alternating colours on the chairs or layering the fabric if you have more than one colour in your wedding you'd like the sashes to reflect. Skip the bow and tuck a single fresh flower into a knot to simplify the sash-tying process. Wired ribbons can make the bow-tying process easier; they lend a rigidity to the form without any additional labour.
If you are considering a high-quality fabric, check rental prices first, because they might be cheaper than making your own.
