Just recently took up the hobby of custom hat making....so I figured on making my own sweat bands as $10 (+ shipping )a pop for premade is quite a high perceantage on the cost of creating a costume hat...so after some reasearch I drafted a template for the leather section out aluminum, just a big curved ruler if you will. So, its big enough to cater for size 6 thru 8...so the top arc would be the circumference..i might scribe mine with sizes measured out on the right side (length of arc=circumference) I know they use a plastic reeding now but I went old school and use 22 gauge spring stainless steel wire (source Amazon) to insert in the bias binding edge added.I hope this helps someone, the question on dimensions and a template seems to pop up on various forums. Oh...mine is based on 1 5/8" wide sweatband btw.
I also used Sheep Leather as my material.
