Side story, FI and I met in a hot tub. I was at a party in one of my friends hot tubs and FI showed up later and sat in the hot tub with us. Nothing sexual or anything, we actually didn't start dating until 6 months after we met.
I was having a hard time thinking of an idea for a card box. Finally I came up with the idea of having the card box be a hot tub. One of my coworkers has been working on it and I got to see pictures for the first time today.
It's so cute I had to share.
The slit for the cards is on the side.
