I looked into packages as self promotion and really liked the idea of having a collection of things to see rather than just one business card like thing. It lets you show off more of your work to potential clients so they really get a feel of what you can do. I'm going to put together a little package of cards, badges, mini zines for my self promo project.
Egg Creatives - nice idea of it coming in a box, the colours and textures match all the products inside.
Malicious illustration, design and clothing promo pack.
Hydro74 - self promo pack of cards and sew on badges.
Meg Hunt promo pack.
Meg Hunt self promo pack - i like how it comes in a decorated brown envelope, simple and cheap to produce but looks really good.
