My friend visited me a few weeks ago and wanted to see the old forge in action. I offered to help make him something to show the GF.
He decided to use my offer to propose! This is the video he showed her this morning, before giving her the finished product.
She said yes!
That is just lovely! 
(And congratulations to your friends.)
That’s a sweet story… but what is the significance of the tooth?
They met working together in a dental related profession.
You know, I bet @dan would love to see that video. (So I just tagged him.) 
Very cute! And clever to make each line a different color so they engraved separately to slowly reveal the question. At least, I assume that’s what you did.
Awww. I love how excited he looks at the end. Glad she said yes!
That’s exactly what I did. Good eye!
Sweet!
