Things You'll Need
Fabric or wide ribbon
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 colors 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 factoring in the cost. A sash should be at least 2 inches wide and 3 feet long. Draw a light dotted line with a fabric pencil along the fabric with your desired dimensions.
Cut the fabric according your measurements; if you are using ribbon, measure and cut the length.
Use a sewing machine to sew a small seam on all sides if the fabric you chose will fray.
Add any trim you may want on the edges of the sash. Velvet ribbons look nice on most types of fabric.
Wrap each sash to a chair and tie it in a bow on the back.
Consider alternating colors on the chairs or layering the fabric if you have more than one color in your wedding.
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 labor.
If you are considering a high-quality fabric, check rental prices first, because they might be cheaper than making your own.
