Oh, dear heavens, I looked at that site, saw all the decimal points and weird measurements and long lists and promptly closed the page!!!
Finding setting triangle sizes is SO easy, REALLY!!
SIDES = measure the diagonal of your pieced block, add an inch, cut a square, cut it on
both diagonals. Gives you 4 side triangles.
CORNER = measure a side of the pieced block, add an inch, cut 2 squares, cut each on
1 diagonal. Gives you 4 corner triangles.
The OUTSIDE EDGE of each triangle will be on the straight grain of the fabric.....and that will keep your quilt top from bias stretching all around, yay!!
The triangles will each be
larger than you need....but this will allow you to trim and square up your quilt without losing any of the points of your blocks, yay!!
And, BONUS, you can even "float" your blocks away from the edge of the main border, so that you can have a narrow 'border' of the same fabric already built in, yay!!
How easy is that?
