My DH is an engineer and has been very helpful to me in every way when it comes to templates and piecing. He just reminded me of the following point he always makes to me. When making a square with many pieces in it, all you have to be off is 1/32" (maybe the thickness of a credit card) on each seam and when you get done doing 4 pieces, you are off 1/8". Miniscule errors in measurement multiply themselves. Don't know if I am explaining it right but here it is another way. If I am off 1/32" on a seam, you have to multiply it by 2 because you are off 1/32" on each piece that is sewn together. Now, instead of being off 1/32" on a seam, I am off 1/16" for the two pieces, etc. Hope this helps. Now, I just wanted to say, your points are so accurate. You did a great job and I love your block.
