Print out the pattern version you like (for right hand or left hand). If you want to make a pair, you don't need to print the pocket pattern for both the right and left hand. Print one and just flip it when creating the opposite potholder.
Get the fabric and batting for the body and place the batting onto the wrong side of the fabric. If you're having troubles keeping the fabric and batting together, a quilting spray adhesive will help baste them temporarily.
Then fold the fabrics in half, with the wrong side inside.
Using your quilting ruler or yardstick and the fabric marker, trace diagonal lines across the fabric, about 2" apart.
Pin through all layers or clip the edges with quilting clips to help all layers stay put. If you spray-basted them, this step shouldn't be necessary.
Start quilting the fabrics by sewing all those traced lines. I like to start from the center out to prevent the fabrics from slipping. Again, if you used the adhesive spray, this shouldn't be necessary so just sew as normal.
Repeat the process for the pocket.
Then trace the patterns for the potholder and pocket onto their respective fabrics and cut them out.
Grab the bias binding for the pocket and clip it to the top of the pocket. Most quilters start attaching the bias binding at the front side, flip it to the back, and then do a stitch-in-the-ditch. As I'm not as handy, I find that this method doesn't give me satisfactory results. So I start by attaching the bias binding to the back of the pocket.
Sew the bias binding with 1/4" allowance.
Flip the bias to the opposite side of the pocket and press the seam well (you can use the iron on steam to smooth it out). Clip in place.
Stitch-in-the-ditch or top stitch the bias binding if you're using my method.
Grab the bias binding for the loop and open it.
Fold the edges in towards the middle and press.
Close the strip again and press.
Top stitch the open edge to form the loop strip.
Fold the loop in half and clip it to the top of the potholder body, with the raw edges out.
Sew the loop to the body using a 1/8" allowance.
Place the pocket piece over the front side of the body (the one without the loop), with the loop end at the top.
Make sure the edges in both pieces match perfectly. If there is some small discrepancy, cut out the areas that don't match perfectly, making sure to keep the oval shape smooth.
Clip the pieces together with quilting clips.
Run 2 lines of basting stitches on the sides. These are temporary stitches that will keep the pieces together while sewing the bias binding. If you are an experienced quilter this step is not needed.
Add bias binding to the raw edges in the same manner as for the pocket.
Flip the loop up before finalizing sewing the binding. This would be done in the second step of the process.
Remove the basting stitches using the seam ripper or embroidery scissors.
