Fold the strip in half and press.
Run a basting stitch along the bottom edge, 1/4″ from the bottom.
Pull the baste stitching to gather up the fabric into a ruffle.
The ruffle needs to be able to go all the way around the hot pad, so set the ruffle aside for now and we’ll come back to it. You might need to adjust the length later.
Two layers fabric, two layers batting.
Pin it on all the way around, tapering the ruffle off of the hot pad at one of the corners.
Pin on a little piece of twill tape, about 4-5″ long, folded over. This will make a little hanging tab. Make sure it is facing to the inside of the hot pad.
Stack the other piece of fabric on top of the whole thing and pin it down.
Sew all the way around, leaving about a 3″ opening.
