I don't understand - if the 3.5" blocks go on the corners and 6.5" block is in the center, then assuming the seam allowances are all the same (I'll assume 1/4"), and you're not trimming, then wouldn't the small blue triangles have to be cut from 3.5" blocks, not 4.25", and the large triangles cut from 6.5" blocks, not 7.25"?

On the corner squares and the center square, you are correct (1/4" seam allowance).
When a square needs to be cut into triangles, they need to be larger to accommodate the additional area to be sewn (the third leg creating the triangle instead of square).
I hope this makes it a little easier. I learned it through trial and error.
very cute !! can't wait to get to all of these !
