Having a senior moment
 

Maybe because I rarely piece quilts the traditional ways, but I need help to figure out the size on the setting triangles on a table runner with the squares set on point. Can anyone recommend? My squares will be 12 inches squares. TIA

I have a tute here that will help you. http://www.quiltingboard.com/tutoria...y-t100648.html
Scroll through the pattern toward the end where setting the blocks is discussed.

i have a 20 inch ruler that has the info on it for every size block/square. love it!

I have that ruler too!

Thanks, Jan.

Here's a link to Bonnie Hunter's site with that info. She provides all the calculations, but if you scroll down a bit, there's a handy dandy chart so you don't need to do the math.
