I opted for a simple 6-segment design, but you can change the number of panels easily.
First I took my measurements. Around my head from the nape, over the ears and across my temples I measure 22in. Over the top of my head from the nape to my forehead measures 14in, but from earlobe to earlobe measures 16in. I therefore decided that the segments should measure 3.5in wide (to allow for a little stretch) and 8in long.
I decided to use ëshapesí to develop this design, so the sloper size used is not important. I went into the Display Pieces dialog box and turned off all the standard garment pieces.
For knitting, you will be making either a circular or flat piece that is 6x the width of this pattern piece. The shaping at the edge of the pattern piece will be accomplished by decreasing at the 1/6th marks. You may want to manually stagger the left and right edge decreases so they don't appear on the same row.
You can see from this short tutorial that you could adjust the sides any way you want to get your desired shape of hat.
