An elf hat adds whimsy to your winter wear. The tall, pointed style, topped with a pompom and trimmed with white felt, is iconically elfish. Choose a color other than green for a look that is less Christmas-like and more forest elf. For a young child, add ribbon to tie under the chin and keep the hat on.
Measure around your head, and from your forehead to the crown of your head. Write down these measurements.
Cut a large piece of craft paper to make your pattern. Tape or otherwise anchor the paper to your work surface. Draw a horizontal line near the bottom of the paper that is 1 inch longer than half the diameter of your head. Find the center of this line and measure up by the distance from your forehead to your crown. Draw a horizontal line at this mark.
Draw the sides of the hat so that they taper in by 2 inches on each side to the line you made above the brim line. From this point, bring the lines together to a tall point 6 inches above the center of the second line. Cut out the pattern.
Fold a piece of green felt in half. Pin the pattern to the felt and cut out, making two pieces. Pin the two pieces together along their sides, leaving the bottom open. Sew along the two side seams, leaving a 1/2-inch seam. Trim the excess fabric to 1/4 inch.
Cut a piece of white felt 2 1/2 inches wide and 1 inch longer than the diameter of your head. Sew the ends of this strip together with a 1/2-inch seam, making a circle. Trim the seam to 1/4 inch. This is the rim.
Turn the hat right side out. Slide the rim, right side out, so the bottom edges line up. Sew around the bottom edge and the top edge, using white thread. Sew a white pompom on the tip of the hat using a needle and thread.
