Hat TopInspired 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.

Using the charts provided (click on either to download a printable PDF) work thelace pattern 8 times per round.

One note about row 6, you should work the K, P, K into the double YO. Do this by unwindign the double YO so that it is one long loop and work your knit, purl and knit into it.

Repeat rounds 19 and 20 [21 and 22] until the hat is 6.75" [7.5"] from the cast on or until it is 1" shy of desired total length.

Work 2 [2] rounds of 1x1 ribbing

Work 8 [8] rounds of STst for rolled hem.




You should only have 2 tails to weave in.

Like most lace items, this piece will look best if you block it.
