I've used a mixture of stamps - my little diver is from Lili of the Valley and the underwater critters etc are oldies from High Hopes.
And then because I enjoyed making the calendar page so much, I made a CAS birthday card version too ...
- AAA Cards #91 - 3rd birthday bash
- Less is More #330 - shimmer
- Simon Says Stamp Wednesday - anything goes
- Word Art Wednesday #284/285 - anything goes
- Cards 4 Guys #170 - I always like red, white and blue as a male colour combo
