Tape the pages together as directed on the pattern pages.

Step 1: Place pattern pieces onto fabric pieces as directed and cut out.
Step 2: Follow directions as on "Top piece A" pattern piece by folding edge over 1/4" and pressing with an iron.
Step 3: Double fold this over another 1/4" and press again with an iron.
Step 4: Now stitch these folds down stitching close to the edge (seen in picture below)
Note: When I sewed this hat I did step 12 before I did step 11. It does work but you have to work the elastic a little to flip it because it is already encased in the middle portion. I realized later it would make more sense to do it in the order I described.
Now you are finished. Try on the hat. How does it feel? If it feels a little bit loose go to one of the openings at the back, pull on the elastic. Pinch it together until it feels like a good fit. Remove hat while keeping your fingers pinched on the elastic. Look how much elastic is in your pinched fingers. Put the elastic in the sewing machine and sew it in a little. Try it on again. Hopefully you have achieved the perfect fit. Remember, you do not want it to fit too tight. I have made this mistake a couple of times and I just get headaches from wearing a hat that is too tight.
