Fold one piece of flannel in half. Place the cutting template on the fold, pin in place, and cut around the template. Repeat for the other piece of flannel.
Unfold both pieces of fabric. Place one on top of the other with the right sides of the fabric facing out. Pin the front and back together around the edges of the fabric.
Sew around the edge using the pressure foot on your sewing machine as a guide.
Make ½” cuts around the edge, cutting close to your seam, but not on the seam.
Machine wash the burp cloth and tumble dry. When it comes out of the dryer the edges will be fringed and fluffy, which is what you want. Trim off any long loose strings.
Notes
Each time the burp cloth is washed and dried the edges become more fringed and fluffy!
