QUESTIONS FOR TRIANGLE SIZES????

Can anyone help me with  the formula for working out the size to cut the  1/2 and 1/4 size triangles.
ie.

*  I wish to put 12.5 in squares on point for a sampler quilt
*  I need the formula for how big to cut the 1/2 triangles that go on edges??
* and... also the corner 1/4 triangles.


I cannot seem to find this in my notes, and rather than guess, thought I might ask the experts - you wonderful bloggers.

*wave* i know that one...

i am assuming that your blocks finish at 12 inches:
sqaures cut for side triangles: 18 1/4" cut on both diagonals to yield four side traingles

you'll need two squares cut at 9 3/8" cut once diagonally to yeild 4 corner triangles..

if your blocks are 12 1/2" finished:
side traingles: 19"
corners: 9 3/4"

these measurements give you exactly a 1/4" point. if you want you blocks to 'float'- cut the bigger size.

hope this helps! anything else let me know!
happy stitches!
