okay ;) somebody willing to comment on the size issue!
i was THINKING about what it takes to do a ....let's round up to 100 x 100.
at that size, i wouldn't dream of small hexes. and i think that size can take large ones. so in the range of finished 10" at the widest measurement, what would you GUESS (this is not a test) is the amount of yardage needed? bigger hexes = fewer seams.
at the other end of the scale, what would you think at 6" finished at the widest?
