a picture of a previous hat and the colors you have in stock would probably be very helpful in selling them more efficiently. and if you are using the knifty knitter witch i presume you are using, you should also add to the description that you could make a brim or not if you have made one before. hope you do well in your sale. i also knit beanies and have made a business out of it by selling my hats for $20 each for some pretty specific designs. also if you are using the knifty knitter, you can make headbands by feeding the extra piece of yarn at the end of it and not cinch it but only tie a knot together connecting the ends together.
