To complete 8 napkins you will need 2 yards of fabric, 1 yard of each print. Contrasting prints make a nice effect when folded.
Cut your one yard lengths into 9" strips.
Fold each strip in half a second time, you will have four layers of fabric.
Using a Cut a Round ruler place the corner on the second fold.
Use the slot for a 18" circle. Since the fabric is cut into a strip this will yeild two semi-circles each with an 18" diameter.
After cutting both fabrics place contrasting pieces right sides together and stitch 1/4" around the edge leaving a 3" opening for turning. Backstitch at the beginning and ending of the seam to prevent the seam from coming open when turning.
After turning press the edges and whip stitch the opening closed. You could topstitch the edging if you choose.
To create the tree effect press the first fold about 2 inches off-center as shown above.
Fold both flat edges back on the first fold to create the exposed layers. And viola! A Christmas tree.
