Calculating setting triangles... HELP??
Good morning, dear quilting friends! (or good evening, depending on your location!) My sweet DIL has chosen a quilt for her first baby (and my first grandchild! woohooo!) but all I have is photograph. I've managed to make the center medallion, but it's on point and I'm stuck figuring out the size of the setting triangles. Now I passed geometry under my own power (not with an A...sigh), but that was 1969... and I can't remember how to calculate this!?! Is there a place here on the QB with directions? The center madallion measures 36.5" on each side... Please help????? and THANK YOU!!!

I saw this on Saturday to cut a square 1.25" larger than your block size. I would try this out on paper and see if it works. Sewing with Nancy was making quarter triangles which is what you want with the straight of grain on the outside edge of the quilt.

If you make a square 26 1/4" and cut it in half you will have your setting triangles.

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?

I have never done it any other way. Never had a problem and trims up perfectly. Love to do on point quilts.
Thanks for your great tip. KIS
peace
