How to Sew Trim to a Pillow. Making your own throw pillows is a great way to stretch your decorating budget. Plus you have the added advantage of getting exactly the pillow you want. One way to spruce up plain pillows is to sew trim on them. It's a simple process. Here are some tips to get you started.
Purchase your supplies. Purchase enough trim to go all around outside edge of the pillow plus a couple extra inches. If you are sewing flat trim on the front of the pillow, purchase the correct length plus an extra inch or two.
Prewash the fabric and trim. Use the same water temperature you plan to use to clean the finished pillow. If the trim and fabric aren't machine washable and you plan to wash the pillow at some point, you can prewash the fabric and trim by hand.
Cut the fabric. Allow extra for a seam allowance.
Figure the length of trim you need. If it is going on the front of the pillow, cut the length and pin it in place on the front of the pillow. If it is going around the edge of the pillow, pin it in place with the trim facing the center of the pillow.
Set the sewing machine to either a straight stitch or narrow zigzag stitch. Sew the trim in place. If the trim is bulky, you may want to put the zipper foot on the presser foot so you can stitch close to the trim.
Put the two pieces of pillow fabric right sides together. Sew the two pieces together. Leave a three-inch opening. Be careful not to stitch any farther in toward the center of the pillow than you did when you attached the trim.
Turn the pillow right side out. Pull out the corners. Stuff the pillow with fiberfill stuffing. Sew the opening shut with a needle and thread.
