The pattern gives instructions for a matching Scarf, Hat, and Mittens

From Shawls and Scarves: The Best of Knitter's Magazine:

Lace is an unexpected venue for Celtic motifs, but our trio of sophisticated accessories is both Celtic and lace.  The Knitters crew voted Susan’s Jaunty cap the most wearable knit hat in many seasons.  The extra long scarf and hat both sport lush, full tassels.  Mittens have warm, wide gauntlets.  Tweedy Donegal wool gives this set pizzazz!

Amazing Twining Lace, p. 35: The scarf (including tassel), uses a little over 2 skeins; 4 skeins should make the set. The first dec rnd of hat: *K18, k2tog, place marker (pm); rep from *. Each dec rnd you will knit one fewer st before the k2tog. Thanks Susan from On the Fringe.
