12. Place the Rounded Corner Template on the outside right edge of one square, aligning as above. Pin and cut.
    
13. Without moving the pieces, place the Rounded Corner Template on the outside left edge of the opposite square, aligning as above. Pin and cut.
14. It's important to keep track of your lefts and rights so the mitts are correctly cut to fit on each end of the hot pad.
15. Repeat steps 11-14 to cut the mitt lining pieces.
    

At Your Sewing Machine & Ironing Board

Assemble the mitts

1. Pin a 3" x 8" strip right sides together with the inside straight edge of each front mitt front piece. Stitch together using a ½" seam allowance. Press seam open.
   
2. Match up the opposite 8" side of each strip with the inside straight edge of each mitt lining piece. Stitch together using a ½" seam allowance. Press seam open.
   
3. You now have two flat mitt pieces. Fold each one in half, matching all raw edges and creating a clean-finished fold along the border edge.
4. Use one folded piece as a template to cut TWO pieces of thermal batting. Remember, I promised we'd do this.
   
5. Sandwich a batting piece in between the fabric layers of each mitt, making sure all the layers are smooth and flat. Using a ¼" seam allowance, machine baste around the raw edges. Do not stitch along the folded border edge.
   

Assemble the front layers

1. Place the batting down first on your work surface, place the front body piece on top, right side up. Place a finished mitt on each end. Keep the raw edges of all the layers flush. Pin the layers together and the mitts in place.
   

Final assembly

1. Layer the hot pad back piece right sides together with the assembled front.
   
2. Pin all around, leaving an approximate 6" opening along the edge opposite the hanger . Just to make sure you're paying attention, in my picture that opening is shown at the top of the photo. 
   
3. Using a ½" seam allowance, stitch around the entire hot pad. Go slowly around the curved ends, stopping as needed, with your needle in the down position, to slightly adjust your presser foot position if needed. Remember to back tack or lock stitch at either side of the 6" bottom opening.
4. Trim the seam allowance and clip the curves. Do not trim back the seam allowance along the opening.
5. Turn right side out through the opening. Use your finger or a long blunt tool, like a chopstick or knitting needle, to help smooth out the curved ends.
6. Fold in the raw edges of the opening so they are flush with the sewn seam. Pin in place and slip stitch closed.
