It is very easy to do but I have trouble explaining things I went to a sewing festival where it was a demo by Hancocks
who was selling the circle cutting tool you sew 2 circles right sides together all around ---make s slit turn and press have a square that fits inside the circle trace around it sew another circle to it on drawn line then turn the orange peel part around and follow and quilt when finished makes a neat table runner I know clear as mud
