Does anyone know how to determine the size of the square required to make the inset triangles on the edge of a quilt? The quilt is put together on point, so I need triangles to fill in the edges and the 4 corners of the quilt. If I use the same size as the quilt blocks, and cut them on the diagonal, they are too small.

bonnie hunter has a formula..

mke sure you use scrap fabric or muslin for a practice run. or even paper!

Here's something I've found (scroll down to the bottom):

Thanks I just printed a copy will save a lot time.

There's a ruler for that. Seriously. It totally takes any figuring out of setting triangles! Plus you cut them from strips instead of cutting huge squares on the diagonal. It's called a setting triangle ruler.

Thanks all, will try these tomorrow after work, just spent the day fabric shopping, life sure is good :)

wow, now tht is awesome, I'll have to check if that is available around here, or order one on line :)

here is one, and with diagrams for using it..

and for those that can't afford to buy a ruler for a 1 or 2 time job:

they do the math for you..just scroll down to see the info

multiply size of square by 1.41 the round up-(so if on point blocks are 12" blocks- x 1.41= 16.92--or a 17" block) to determine the size square to cut diagonally twice for setting triangles.
