An Antarctic Hat (Part II)

I recently finished my Antarctic Hat. This post describes how it was made and publishes the pattern. Since I began by posting the finished hat, I’ll continue to work in reverse order.

The final pattern is seen on the right. Click on it for a full size image. The original pattern is shown below. Annotations on the final are either doodles while I was bored, notes about stitch reduction or type (ocean v. land), or markers to remind me where I was when I took a break from knitting.

For each stitch, I simply looked at the pattern, determined what box I was knitting, and decided if it should be ocean or land, and if it was land if it should be green, brown, or white.

In order to make the pattern I began with with the NASA Blue Marble image, and wrote some image processing code to replace the ocean with white (just to save some ink and have extra space to take notes). I knitted a swatch to determine I wanted X stitches, and then placed X gray boxes evenly across the page. A little bit of extra work was done toward the South Pole in order to have the increases mapped onto the pattern.

My X came out to 108. If you wanted to use this pattern with a slightly different stitch count you can probably just add or remove a few columns from the Pacific and Atlantic basins without much effect on the proportions of the planet.

I chose to begin at the Pole and increase because it allows me to take the hat off the needles and try it on my targeted wearer and then continue knitting if necessary. Beginning at the rim and working up leaves less room for adjustments. The first red line is the equator, and the second was my original estimate of where I would stop. As you can see from the finished product I ended up knitting farther north, and even then adding the white-and-black map border.

I realize I’ve been calling this the Antarctica Knit Hat but it is really the entire southern hemisphere and almost half of the northern hemisphere. It includes Antarctica, all of Australia, New Zealand, Micronesia, and South America (although I forgot a stitch for the Galapagos), almost all of Central America, Africa, and India, parts of the Arabian Peninsula and Asia, and even a pixel / stitch or two of North America.

    This is almost exactly the kind of hat I want. Are you planning to sell or license the sale of such hats? Actually, I was thinking of the northern hemisphere, since it’s more recognizable…

    Why do I want such a hat? I have decided to “Surrender, Dorothy” to the thinning hair. The bar code fashion just isn’t me, so I’m planning to shave all of it. However, if anyone says anything about it, I want to whip out my global hat, pop it on my head, and answer “global warming”.

    Anything for a joke?

    Not sure if you (as the author of the blog) can see my email address, and sure not going to post it here, but I have told the system to notify me if you reply to this reply. Hopefully we can get in touch if you want to get in on the joke, so to speak.

    Hi Shannon,

    I recently made the northern hemisphere pattern and will be knitting that soon. I’ll post back here when I have it finished.
