Start by cutting your fabrics into 2 1/2" squares. I used about 24 squares but if you want to have a little more room to work when quilting the potholder add 6 more squares.
Match the squares in pairs, right ides together.
Chain sew all pairs with 1/4" allowance then separate the pairs by cutting the thread with small scissors.
Finger press the seams open then press well with the iron on steam.
Then continue pairing the fabrics, right sides together until you form rows of squares. Press the seams after each step.
Once the rows are formed, match them in pairs, right sides together to form the patchwork panel.
Cut the batting, in the same size as your fabric panel. You need 2 pieces of batting for each potholder.
Cut a piece of fabric for the backing, in the same size as the patchwork panel.
Quilt the patchwork panel
Sandwich the 2 pieces of batting between the front panel and the backing fabric. Add a few pins through all layers or use basting spray to keep the layers together and prevent them from moving when quilting. I didn't have any at this time but using enough pins helped me manage this issue pretty well, the fabric shifting was minimal.
Trace diagonal lines across the front panel, using the corners of the fabric squares as guides.
Sew these lines from left to right and again from right to left (so that you quilt rhomboid shapes across the patchwork panel).
Transfer the pattern onto the quilted potholder and cut out.
Make the pockets
To make the pockets you'll need one piece of batting and 2 pieces of fabric for each pocket (so 2 battings and 4 fabrics in total). I used different fabrics for the front and back of the pockets.
Sandwich 1 piece of batting between 2 pieces of fabric to form a pocket then repeat for the second pocket. Pin through all layers or use basting spray to keep the layers together while sewing.
Quilt the pockets using straight stitches, sewing squares across the entire surface of each pocket.
Attach bias binding to the bottom raw edge of each pocket.
Attach the pockets to the potholder
Clip the pockets to the back side of the potholder (the one that is not patchworked). Sew around the entire potholder with 1/4" allowance. This will help with keeping all pieces together later when you'll apply bias binding to the potholder.
Attach a small loop (this will be used to hang the final potholder when not in use). To make this loop, simply fold a small rectangle of fabric in half and press. Then open the strip, fold each half and press, then fold back to the initial fold. Sew the strip to the open side, then fold it i half, lengthwise.
Trim the seam to half.
All that is left to do now is covering all the raw seam in bias binding. I used 2 1/2" bias binding, folded in half to 1 1/4".
