My husband and I are SCUBA divers and this is the birthday card I made for his birthday last weekend. It is for this week's Case the DT challenge. I cased Theresa's Under-the-Sea card (http://stamptv.ning.com/photo/under-the-sea-15?context=user).
The changes I made are: instead of sponging the background, I airbrushed using Copic markers, I changed the orientation to landscape and I used stamps from the Just Keep Swimming set.
There are a few more details on my blog, if you're interested:
Thanks for looking!
