We call a child's mind 'small' simply by habit; perhaps it is larger than ours is, for it can take in almost anything without effort.
I've always drawn a lot. I like the idea of turning a 2-D sketch into a 3-D thing very quickly. And clothing is really good for that. You can draw an idea in the morning and you can see it by the end of the day. I think if it were something like a four-month process to get from the idea to the final thing, I would get quite bored.
