onPoint
Calculate setting triangles and corner triangles for on-point quilt layouts. Get exact cutting sizes to achieve perfectly flat edges when blocks are set diagonally.
Frequently Asked Questions
What does 'on point' mean in quilting?
Setting blocks 'on point' means rotating them 45 degrees so they sit diagonally. This creates a dynamic design where the blocks appear to float, and requires setting triangles to fill the edges.
How do I calculate setting triangle sizes?
For side setting triangles, multiply the finished block size by 1.414 and add 1.25 inches. For corner triangles, divide the block size by 1.414 and add 0.875 inch. Our calculator does this automatically.
Why do on-point quilts need corner triangles?
Corner triangles fill the four corners of the quilt top when blocks are set diagonally. Without them, the corners would be incomplete and the quilt would not have straight edges.
