- Print out the free pattern. Once you've printed it out, cut the three pieces out and tape them together after matching the lines and letters along the edges. 
- Start by pinning the pattern on the flannel (folded so pinning through two layers) and cut out around the outer edge. 
- Also cut out one of the Cotton Batting (or fleece iron on interfacing).  
- Place the two pieces of flannel right sides together with the batting underneath. Pin all three together around the outside edge of the fabric.  
- Sew a straight stitch ⅜ inch from the edge all the way around the edge of the burp cloth, leaving an open edge that's about 3 inches wide. Backstitch at both the beginning and end of the seam. 
- Clip little triangle wedges out of the seam around the rounded raw edges of the burp rag, being very careful not to cut into the seam.  
- Turn the burp rag inside out (right side out) through the opening you left on the edge. 
- Press out flat and turn the edges of the opening to the inside along the seam line. Pin the opening closed. 
- Stitch close to the edge all the way around the burp cloth and over the opening so it is stitched shut. 
- I went ahead and sewed straight lines across the burp cloth about every two inches to keep the cotton batting from bunching up when washed. You could make a cute criss-cross pattern, or use decorative stitches  if you want. It's kind of "quilting" it together. 
- Now make a few more to create a giftable set!
