This quilt cornerstone calculator helps determine how many cornerstones are needed when adding sashing between quilt blocks. Enter the number of blocks across and down to estimate the total number of cornerstones required.
How to use calculator
Enter the number of quilt blocks across and the number of blocks down in your quilt layout. The calculator will estimate the total number of cornerstones needed when sashing is used between the blocks.
Explanation
Cornerstones are small squares placed at the intersections where sashing strips meet. They help stabilize the quilt layout and add decorative design elements.
When sashing is added between blocks, a cornerstone appears at every intersection of the sashing rows and columns.
Example math
If a quilt has 6 blocks across and 8 blocks down:
(6 + 1) × (8 + 1)
Which equals:
63 cornerstones
