I thought it would be easy to buy a pirate hat but everywhere was sold out, so we designed our own from black cardboard, glue, tape, staples and gold braid. It took much longer than expected but turned out rather well.
The parrot was non-negotiable. The pirate in the book (I wish I had a pirate suit by Pamela Allen) had one, so we had to have one too.
Thankfully there was a parrot finger puppet in the toy box (from Ikea). Some pipecleaners for feet, some green feathers for wings and two big safety pins to attatch it to the shoulder and the pirate parrot was ready for action.
Every pirate needs some treasure. Our gold and silver coins were made from bottle tops flattened out with a hammer. They smell a bit beer-y but that's okay.
The pirate sword was cardboard covered on both sides with some sticky-backed foam found in the 'useful stuff' in Dad's shed. Apparently it is used for concrete slabs? It made a nice soft sword that shouldn't cause any damage.
One of his mates had a telescope. Of course Pirate Jack noticed, turned to me and said "Mum, where's my pirate-scope?".
