After stitching the entire outside border of my Etruscan Diamonds Square, it was time for the whole thing to meet up at the bottom right corner. I was on the 80th X in the border, and here's what happened:
I counted it all just fine - it met perfectly! Now for an adult beverage. Disaster averted.
This part always makes me nervous.
I don't always stitch the outside border first but, for this design, it seemed like it would be so much easier to orient the larger motifs against the outside X's than vice versa. And I was worried that being a stitch off would be super obvious, so I double and triple counted all of the X's as I went.
