This is how the hat is sewn:
Print out the template and cut it out. A seam allowance of 0.5 cm is already included. Now transfer the template in the fabric break to the fabric and cut it to size
Now fold the fabric right sides together in the fabric break and pin everything in place. Close the outer edges with a straight stitch and then trim the seam with a zigzag or overlock stitch. Of course, if you sew with an overlock machine, there is no need to clean up the edges. Unfold the hat and place the seams that have just been closed on top of each other. Tighten everything again and close the upper curves with a continuous seam. Clean them up again
Turn your hat around
Bind the lower edge of the cap with a zigzag stitch. Now you can turn the cap twice.
