Your measurements look fine, if in fact all your 3" blocks are actually 3" finished
BUT .. I agree with
Prism99.
I too always cut oversize . When assembling the setting triangles to the block, I match the center of each so I have extra on each edge. Then each row will get squared up and straightened. Then after I assemble the whole quilt, I will square up the sides. I myself would rather have to trim off, than not have a straight edge.
