Sew a warm shearling hat

Step 2 Create the pattern

To begin this project, we need one simple measurement to make our patterns.
Wrap a single layer of shearling around the head to be fit and measure just above the ears.
On this hat the measurement is 23 inches.
Draw a rectangle 23 inches long by 8 inches wide to which 1/4 inch is added for a seam allowance on all sides.
The second part of the pattern is only a little more difficult.
Draw an oval with a circumference of 23 inches. ( I measured the opening of a felt hat for length and width of the oval.)
To raise the top up about one inch I added a second oval one inch (+ 1/4 inch seam allowance) outside the original line.
This of course is an oval that is greater than 23 inches so I placed four darts around the circumference to bring it back.  They are about 2 inches deep toward the center of the hat to give it a more slanted top.
Cut this piece out of the paper.
