From Lace Style:



For the most part, lace patterns do not make insulating fabric and are rarely considered appropriate for warm winter hats.  But by layering a decorative lace pattern over dense stockinette stitch, Mona Schmidt found a way to make this hat both lacy and warm.  Mona worked the layers in contrasting but coordinating  colors--orange and red--and experimented with lace patterns until she found one with plenty of large eyelets to reveal the solid layer underneath.
