I also just had a look on Makeesha's blog at the other cards & there is another Ahoy Matey colour challenge card..so lots of ideas...shame it's retiring & in fact sold out already.
Anyway, I used the colours as mentioned above. I also used sanded background stamp, family phrases, It's your birthday (retiring), bold brights buttons (retiring, so I used a few to make the most of them!).
All the best for the week ahead & another week closer to the new catalogue!
