Step 1: Fitting the Hat
Measure with a piece of string the circumference of your head; this is where the bottom of the hat will lay, so consider where you want your hat to rest, also don't forget about your ears. I always have hats that are too small to include my pony tail so I was sure to include that in my calculation.
Now cut a piece of duck tape of that length and fold it in half the long way so that the sticky sides come together. Make a circle with that piece of tape and then tape it together.
Now measure with a piece of string from the front of your forehead and the back of your head. Imagine this is going to form the top of your hat so you will not want to make it too small or large. Again cut a piece of duck tape to this length and then fold it in half the long way so that the sticky side will be on the inside. Now cut another piece this same length and do the same thing to it as you did to the pieces before. Make an X with those two pieces and tape them together. Then take the ends of the two pieces used to make an X and tape the ends to the circle that you made in the start.
Step 2: Brim of the Hat
Now we will be making the frame for the brim of the sun hat. Think about how long you want your brim to be. Mine is about 6 inches long but you can try making it as long or as short as you want to. Measure out a piece of duck tape that is the length of the brim that you want (in my case 6 inches) and fold it in half the long way so that the sticky side is facing in, just like we did for all for all of the other pieces that we made so far. Now make about 8 or as many as you’d like of these strips. They will outline the brim of your hat.
Once you have those brim pieces cut and taped together, tape them to the bottom of your hat frame so that they stick out (like the brim of a sun hat). Once they are all attached, cut pieces of tape that are folded in half and tape a circle around the outside of those little brim pieces.
Step 3: Finishing It Up!
Keep in mind that this hat is made out of tape so make sure that there are no sticky parts, especially on the inside.
