Using 1/2" seam allowances, stitch the bottom to the figure front and figure backing, right sides facing. Ease the curve in the bottom piece to fit along the bottom edge of the figure between the two dots. Do not stitch beyond the 2 dots.
Stitch the backing to the figure front, right sides facing, along the side edges of the figure. Leave a 3-inch opening along one side edge, 1 inch from the base.
Clip the curves as shown to reduce bulk, allowing for a smooth curved edge after turning. Use caution - clip close to, but not through the seam stitching.
