Cause after extensive research (lil laugh) ..I read that having the tip helped you line up your hexagons better.
By the way, how do you like your Star Maker 6?...When I first started quilting/researching quilting ...I had seen a vid of kay woods making her tumbling blocks quilt...I fell in love with it...I ordered the pattern and whatever ruler it took to make it....
I just searched all my stuff to see if it was the star maker 6...And couldnt find it anywhere grrr.. But, I do believe that was the one...I've yet to try it...I didn't find much on this site when searching Kaye woods..
