Jack got the building blocks that we have in the house (they were his many moons ago, now played with mostly by Toby & Noah) and arranged them into the pattern he wanted. He then got a ruler and drew some guidelines. He added it all in pencil then once he was happy he drew it in felt tip.
He added the letters then as a final thought put the ".com" at the bottom (Jack always introduces himself to new people as "Hello, I’m Jack Henderson from Jack Draws Anything dot com").
The colours are the same as the blocks in our house.
He then suggested as a final final thought to put a hand coming down which was responsible for building the blocks and thought that he could draw round his own hand. He did and even added the fingernails.
Voila, job done.
