BINGO!!!! this way, if your seam width is not that accurate 1/4" you still get them cut in squares.
That being said ... it is vital that all the seam widths of all the stratas be exactly the same, so that all the tri-sets are the same width. Then once you have them all the same width, cut the squares at the same width/length.
