Wow! Thank you for taking the time to make up that demo and photograph it.
That's exactly the information I needed. For better or worse, patience and attention to detail are part of my character. Sometimes it's a curse, especially if you ask my wife.
Just a few questions if you don't mind...
To start, do I just tie a knot at the end of the thread so it doesn't pull through on the first stitch, or do I make a single stitch and tie that as a loop to start off? Or is there another method I should use?
Similarly, what's the best way to tie off the end when I'm done?
Is it best to do a repair area with one continuous thread back and forth or doesn't that matter?
