I have done this pirate wobble card hoping to enter it into Daring cardmakers challenge (if I can figure out how to do it lol).
I drew round a plate onto Kraft card before cutting out to create the wobble base card, I then drew on
the lines for the effect of wooden planks. The portholes were created with a 1" circle punch using the same
card as the base, I then used a smaller circle punch for the windows.
