For each burp cloth, use a rotary cutter and mat to cut a front flannel piece and a back minky or terry cloth piece that each measure 12x18".

It is entirely optional, but I like to round off the corners of my handmade burp cloths to prevent the corners from being too bulky. If you want to do the same, trace the corner template (linked above) onto each of the four corners of both pieces using a fabric marking pen, and trim the corners to a curve.

Place the two fabric pieces together, right sides facing, so that all of the edges/corners are precisely aligned. Pin. Using a 1/2" seam allowance, stitch around the perimeter of the pinned pieces, leaving a 3" opening for turning.

Trim the seam to 1/4" to reduce bulk, leaving the unstitched opening untrimmed. (This will make it easier to press and stitch the opening shut in the next steps.)

Turn the burp cloth right side out through the opening. Use a corner turning tool to make the seams and corners nice and crisp. Press the burp cloth flat, tucking the unstitched seam at the opening toward the inside, as shown. Pin the opening shut.

Topstitch about 1/8" away from the edge around the perimeter of the burp cloth, closing the opening shut as you stitch. Your project is complete!
