THINGS YOU WILL NEED:
- (Optional) Go to this link to get the template for the hat piece shapes and PRINT 2 OF THEM: https://www.facebook.com/papermodels93/photos/pb.482804608495518.-2207520000.1399249921./525440960898549/?type=3&theater
(You may have to enlarge the picture. For an average sized head, make sure the bottom part of the two front crown pieces are about 4 inches wide. If you have have a smaller or larger head, then enlarge or shrink the picture just a very small amount from the average size)
- 1 or 2 extra pieces of regular printer paper
- Pencil
- Colored penicils (optional)
- Glue
- Tape
- Scissors
- Thin pieces of cardboard
- PATIENCE!!!!!!!!!!
The height of the hat should be about 4.25 inches tall, and the length around the hat should be about 25.25 inches around (this does NOT include the length around the bill).
Also, you can leave a video response of the hat you made from this tutorial, I would really like to see them!!
