The 10" template is called a "Twister" and the 5" is called "Lil' Twister". My lqs has them. JoAnns does not. There is a tutorial on how to make these is here on the board. I bought the template at our Sew Expo. Last week I bought a charm pack and some yardage for the border. Then I got the flu. Hoping to get to it this next week.
Whoever makes one should post their pic so we can share:-)
