Used to describe either:
1. An all over pattern with no particular sense of a centre, or any part which is significantly more important than another, making pattern matching either unnecessary, pointless or arbitrary. However, as all printed patterns will have a repeat of some sort, there will always be the potential to match the pattern; this is often wise, but it really comes down to the choice of the designer and/or maker
3. A hand painted wall or fabric that has no repeated image–for example something resembling marbling, a clouded sky, or landscape. The overall image is clear and planned, but the patterns within can be described as random.
