Question regarding squaring up blocks
These blocks are 13 1/2" square.
I do not have a large square ruler this size.
What will be the best way to square these blocks up?
I do have the large cutting mat. Would I somehow lay the finished block on the mat and place two of the corner points on this diagonal line and trim from there?
I know I am not explaining this very well but perhaps you can understand what I am trying to ask.
