Pirate ship pinata - cannon hatches

I wanted to give Angelo's pirate ship pinata a little more detail - so I figured I'd give it some cannons. What's a pirate ship without cannons ?

I started by figuring out the dimensions of a cannon hatch housing I could fold from a single piece of cardboard. I came up with this :



The next step was to score the lines, and fold initially :



Then it was a matter of hot-gluing the housing tabs to make it stay together, adding in a cardboard tube for good measure.



Viola ! Then I just had to repeat that another three times, throw together a small cardboard hatch, and hot glue them to the ship body :



And there we have it !



It doesn't look half bad !
