For example, the 2.5" strips become 2.5x1.333=3.8 +.5=4.3, and 18.5 x 1.333=24.66+.5=25.16. The unfinished rectangle is then 25.16 x 4.3. The block itself is a square center surrounded by an 8 point star and echoed by a larger 8 point star, similar to a sawtooth star.
You multiply the finished size, not the cutting size.
So for a 2.5” cutting size, you subtract 1/2” to get the finished size (2”), then multiply by 1.333 to get 2.66” (slightly larger than 2 5/8”) then add 1/2” to get slightly larger than 3 1/8”. For the 5” square, you subtract 1/2” to get the finished size (4 1/2”), then multiply by 1.333 to get 6” new finished size then add 1/2” to get the new cutting size of 6 1/2”. Etc.
