Simple lace pattern knit on larger needles than the dk-weight yarn requires for a lacy, open look. Usually just one 50g ball of dk weight yarn is all it takes! Block it firmly to give it a nice shape and show off the eyelets? I blocked mine on a soccer ball. Worked like a charm. I?ll say it again-- this hat?s shape is greatly improved by BLOCKING! Blocking is your friend! BASIC SKILLS NECESSARY simple lace knitting in the round keeping accurate stitch count GAUGE 4.25 sts = 1 inch in Stockinette stitch BEFORE blocking SIZING / FINISHED MEASUREMENTS one size fits most. Brim is fairly stretchy, so if you have a small head use a smaller needle for ribbing.
