Martello towers defended British coastlines during the 19th century. Each small, round tower supported a single cannon, set on a rotating platform that allowed 360 degrees of artillery fire.
Mini Martello is worked top-down, both in the round and flat, using short rows and staggered increases to create the concentric offset ovals. You will need 4 pairs of different stitch markers; counting is required.
This hat is especially designed for gradient mini sets from A Hundred Ravens. If substituting yarns, you will need about 40 yards each of 7 different colors. Mini Martello comes in four sizes; in all cases, the top is worked the same, and the sizing is achieved by more/fewer decreases before the brim. (Sample is size M.)
