Cut out the pieces using the pattern. Cut 5 to 7 thin strips (6 to 8 inches long) for the trimming.
Sew together the 4 pieces of the hat body. Pay careful attention during construction to make sure the seams are all on the same side (machine stitching it difficult to rip out of felt). At this point the hat should look like this. Seam allowance is figured to be the width of a standard presser foot.
Hat body turned inside out.
I cut away all the excess fabric on the the seam allowances after I took the photo.

Hat trim piece.
Gather and stitch the trim piece approx. 1.5 inches from each end.
Hand stitch the trim piece to the front of the hat. Let the trim stick over the edge of the hat body a little.
Hand stitch the trim to the hat according to your own taste.
