A Hat Using Garment Designer

Rescued post - originally posted 10 December 2011

Someone recently posted pictures of a sweater and matching hat. They had designed the sweater using Garment Designer, but I misunderstood and thought they had designed the hat too. While I was corrected about this, it got me thinking about whether it would be possible to make a hat pattern using Garment Designer.

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 ‘shapes’ 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 the hat, I selected Shape 1 from the Extras menu, and set the shape to be Triangular, Curved-Medium. I also displayed dimensions.

I selected the bottom line of the triangular shape and dragged it downwards until the height measurement was 8in for the upper section of the side.

I selected the point at the centre of the bottom edge and moved it upwards until the measurement for the height of this segment disappeared completely, then adjusted the curve control points until they completely flattened this bottom line.

I selected the outer point of the bottom line and brought it inwards until the width at the bottom was 3.5in (i.e. 2x1.75), then adjusted the top of this line segment and its control points until the line at the edge looked ‘right’. In my case this proved to be a line that is 5.66in high (from the statistics on the bottom left of the window), perpendicular to the bottom edge at the base, and with only a very small curve inwards at the top. 
The final step is to reshape the curve at the top to flow more smoothly from the lower section.

If you are sewing, add seam allowances now, print the pattern and cut 6 identical pieces from fleece with the greatest stretch going across the 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.
