If it had been a gift from me, I probably would have engraved a verse from 1 Corinthians 13 on the inside portion of the panel. The customer gave me artistic license but I didn't want to push it not knowing the couple or customer personally. I thought about doing a hidden compartment but I didn't want to do too much to the top. It was less than 3/8" in thickness and I didn't want to ruin it.It is too late now, but it made me think it would have been nice to "hide a secret" on the underside of the lid - like a nice saying or sentiment, maybe lasered in or a "pocket" where a card would fit...
