LOVE Hexies!! Easy to do, portable, you can make hundreds before you have to decide exactly the pattern you want to use!! I also use the Brandy mylar hexies but have found I can use the XL paper punch to make 1" hexies from card stock. I prefer the mylar hexies but the paper punch was much cheaper in the long run. Also you can print out 1" hexies from
http://sewquickly.com/1-hexie-template-free-download/ but there are multiple sites. Lots and lots of videos on line also. As with everything, some people love them, some hate them. Give it a try!
