A scarecrow hat is not only made of straw, but is floppy in nature. Whether you're making a scarecrow hat as part of a Halloween costume or for a school play, create your own hat at home using some basic sewing skills. Save money by reusing fabric you already have. When you're done, the scarecrow hat should look old and tattered.
Measure the circumference of the head of the person who is going to wear the scarecrow hat. This is the distance around the head. It should be measured on an angle for a comfortable fit as hats are usually worn on an angle.
Divide the circumference by four.
Draw four triangles on the back side of a piece of fabric. The base of each triangle should be one-fourth of the circumference. The other two sides should be 7 inches long.
Cut out the triangles and sew them together, side by side, along the long sides. This will form the base of the hat.
Draw and cut out a circle of fabric that is no smaller than 24 inches in diameter. A compass may come in handy here. This will be the brim of the hat.
Cut out a circle in the middle of the brim. It needs to be big enough to fit on the person's head.
Sew the inside of the hat brim to the base.
Decorate the hat with pieces of straw. Gluing on a plastic flower or a few plastic leaves to the brim of the hat will help create a one-of-a-kind design.
