Kennedy, the Properties dimensions on the first grid are 854X635 pixels and on the second grid they are 789X635 pixels. Are these the correct ones we should have? Thank you so much for spending the time to make this tool and share it with us. I'm sure I will find it helpful. I'd really like to start hexing babies again since my eye surgery, but the thought is a little daunting. I'm sure this grid will help a lot.
