When I started out making these gifts, I had no previous plan or even a rough visual in mind.
All I knew was the personality/preferences of the two mothers-to-be, and the gender of one baby.
There were two major design 'problems' to work with:
1) The shape of the pig is in no way symmetrical. Even the location of the coin slot isn't centred in any meaningful position. Because of this, there were a lot of things I wanted to do that seemed great in theory, but just didn't look good when you actually laid it out on the piece.
2) Almost any design on the back of the pig... ended up looking comically like a piggy anus. While this was... amusing, it also resulted in discarding many ideas.
I spent a full two days looking through books and roughing out sketches (using a black micron pen) on the surface of the porcelain pigs before I finally decided on a lotus design for the girl baby (hereafter known as Lotus Pig), and a gender-neutral Chinese influenced design for the baby I didn't know the gender of (hereafter known as Sleepy Pig).
I didn't take many pictures because most of the designs were wiped clean before they looked even remotely usable.
Arabesque look on the top, and a sharper design on the bottom.
