This 1920s-style cap gets its name from Mann Library at Cornell University—a beautiful building that taught me to knit. To thank this fine facility for housing so many knitting books, I have made this hat in its honor, taking inspiration from the architecture of the library.

The hat features a trellis-lace cap, a stockinette band with purl ridges, and a feather-and-fan edging. It is knit in the round and uses a provisional cast-on—the cap is knit from the bottom up, and the band and edging are worked from the cast-on edge downward.

Knitty.com provides some very helpful guides for some of the techniques used in this pattern. Instructions for a provisional cast-on can be found here and instructions for a flexible bind-off can be found here. If you find doing a provisional cast-on with a circular needle to be difficult, as I do, you can cast on to a straight needle and then transfer the stitches.
