I made this brim hat before and tried for adult and for the season for christamas. hat crown circle diameter is 7.5” ht is 8.5” width is 23”. commonly while crocheting depends upon the crochet yarn the size of the hat differs, if the yarn is thick you can skip some rows and if the yarn is thin we should make some rows. have to make the requirement for the ht of the hat…can use for personal use and make to sell also. please link back to my pattern page.. i didnt add the finishing of hat, that is commonly know to all crocheters even for beginners also. at last stage have to cut the yarn and pull out of the st and at the back side of the hat have to st with the hat for good and neat finishing
