Core Hat is a structured, machine-knit 1×1 rib hat with a neat architectural shape and a professional finish.
It uses seamed wedge crown construction, resulting in clean crown seams that are virtually invisible thanks to the early edge preparation.

This pattern is written for standard gauge double-bed knitting machines (e.g. Brother KH 890 / KR 850) and is suitable for beginner to intermediate machine knitters who want a reliable, repeatable method for shaping a classic rib hat.
