Pattern Description from MarnieMacLean.com: “Inspired by a motif from A Gathering of Lace the Halley’s Comet Hat makes one think of a bursting light with a trail behind it. Halley’s is the most well known of the comets and has been inspiring humans since at least 240 BC.

From the front, the eyelets and decreases are neither fussy nor overwhelming. It’s a perfect hat for people who generally find hats too warm, but who get a bit cold without something on their head. A bit of ribbing before the hem keeps the roll under control. This hem draws interest to the eyes. It’s a great feature for people with oval faces, breaking up the length and adding a little width for balance.

While complex in appearance, there are really only 19 rounds for the center motif while the rest of the hat is worked in a simple two round repeat. I do not suggest trying to adapt this to be worked flat, this hat is best worked in round. Blocking allows this hat to fit a myriad of sizes, so this pattern is only written for size S/M and L/XL. I would be surprised if many women could wear a hat as large as the larger version. If you want to downside the hat, I highly recommend doing so by working at a smaller gauge.“
