I went very technical , shysal , but for each step had to find out how to do it - I copied the GN choc cake photo to Photoshop, found pics online of chicks (for spring) and a floor pail (for the anagram) and fiddled about changing sizes of things and trying to make a row of chicks look as though they were marching around the side of a round cake. Stuck pics of chicks and pail onto pic of cake OK once I had worked out how to. Added text of the date and "FLOOR PAIL" in tasteful yellow and green.
Then I lost it all before it was saved. My masterpiece!
