I've got 12 1/2" unfinished blocks that I'm setting on point, then want to add the triangles to make them square. To avoid having bias edges on the corners, would I cut them at 12 1/2" with one diagonal cut?

Four things you can't recover: The stone.....after the throw. The word......after its said. The occasion.....after its missed. The time......after its gone
I hope this will help you.

Thanks Ranger. I guess I wasn't trusting my math skills today (I was coming up with the right answer just didn't KNOW it was right). That's what happens when you try to do math with a headache. LOL

The quiltville site doesn't explain where the 1.41 factor comes from. If you have a 1" square, and cut it into a triangle, the length of the diagonal is calculated from the square of the sides, so 1 squared + 1 squared = 2. 2 is the squared length of the diagonal side (hypotenuse), so you have to take the square root to get the length, and the square root of 2 is 1.41 .
Changing the length of the sides, the 1.41 becomes the factor to multiply by the length of the sides.
sorry, had the wrong link.
SIDE SETTING TRIANGLES:
1. Measure your block ON THE DIAGONAL and add 2" to that measurement and cut a square.
2. Cut that square on BOTH DIAGONALS. The long edge will be on the straight grain and will be set along the EDGES of your quilt top.
CORNER SETTING TRIANGLES:
1. Measure your block along one side, add 2" to this measurement and cut 2 squares.
2. Cut these squares on ONE DIAGONAL. The short sides will be on the straight grain and will be set along the corners of your quilt top.
No math. No lost block points. A little "float" allowed. A stable, wonderful setting!

Jan, I've been quilting many years but have only been on QB for a couple months. I have really enjoyed reading your posts, and have even learned some new things from you. Just wanted to say thanks for the wonderful things you share. Even us old dogs can learn a new trick or two.

Good friends are like stars; you don't always see them, but you know they're always there!
Added link to my favorites. Thanks!
