And so it goes
Cut the outer fabric and lining twice each, adding approx. 1.5 cm seam allowance, according to the one you have Pattern in hand.
Place the cut pieces of outer fabric right sides together and sew the belly sides together. Do the same with the linings, but leave a turning opening in the middle of the belly.
Now turn the lining fabric to the right and push it into the upper fabric, which is still on the left, so that upper and lining fabric are now right side out. Now sew the closure side. Then turn the bag through the turning opening in the lining and close the turning opening.
Mark the middle and side points of the pouch and fix the clip fastener in the next step by attaching Pins. the clip fastener with a kind of backstitch, always pricking back into the penultimate stitch and then leading the needle forward in double stitch length.
FINISHED!
