Step 1: Materials
-Black felt or fleece fabric, MUST be fairly stiff to stand up a bit.
-gold felt or fabric, contrasting felt for letter H (Could also use house colors, e.g., green and silver in an S for Slytherin)
-Tailors chalk, or other light colored writing tool
-needle, or sewing machine
-hotmelt glue or more thread to attach the crest
Step 2: Measure and Calculate
You'll be cutting out a piece of fabric a little wider than a quarter of a circle.
Take the measurement of the circumference of your head, multiply it by 4 and plug it into the equation for finding the circumference of a circle (2 pi r=C).
To see how I did this, check out the graphic:
(it also has the awful sketch from the hogwarts crest.)
Take the measurement you get for R the Radius and add an inch or so for your seam allowance.
Step 3: Draw the Pattern and Cut Out
Measure 15 inches (or whatever your r+1 measurement is)down each side.
If you have more fabric than I did, you can make your angle greater than 90 degrees, which will have a better shape.
Now, use your measuring tape or a piece of string to make a compass to draw on your hat's outline.
holding the chalk against on end of the string in one hand, pin the other end of the string to the tip of the hat with your other hand. Swing the chalk from one measurement mark to the other in a curved line.
This creates the line for the base of your hat. Cut along this line.
Step 4: Pin and Sew
Pin up the straight side, and try it on your head for fit (please watch out for the pins)
If the fit is wrong, make your changes now. Much easier to mess up at this point and reposition pins than to sew it wrong and have to rip the seam out.
If it fits well, you're ready to sew it up!
Use your machine, or sew by hand, and make one straight seam up the side.
I wanted my hat a little shorter, with a more rounded tip, so I angled my seam in a bit towards the top (see last photo)
You can also turn the bottom of your hat up and hem it, but since we are using fleece or felt it will not unravel. A hem would also add extra bulk...
Step 5: Finish the Hat
Leave 1/4 inch for a seam allowance.
Turn your hat back right side out, and poke a pencil into the tip to turn the tip all the way out.
Step 6: Make the Crest
Use the gold (or lighter color) to cut out a shield shape. I drew mine freehand while looking at some photographs. You could also print one out and trace it. Cut out a letter in the darker color (or an animal to represent your house). You can sew, or glue these on to the front of your hat.
You can wear your hat pointed straight up, or let the point drop.
Enjoy the instructable, and if you make one, message me and I will add a picture of you wearing it if you like!
