If, like me, you don't have these colours just use something close - I used a Matt silver, More Mustard and a generic green to stamp on my card. I also used two of my 'go to' stamp sets, Wetlands and Work Of Art. Do you have favourite stamp sets too? Ones which you love to use over and over again? I've teamed them up with the Hello You thinlets die and Best Ever Dad, to make the sentiment.
I used the sketch from CAS(E) This Sketch
I used the silver and the green stamped and then stamped off to create the four panels. Then I stamped the goose in More Mustard, carefully positioning the image with my Stamp-A-Ma-Jig so that the plumage of the bird would match up.
Finally I added the Happy, cut out of green card stock and stamped part of a sentiment in the silver.
