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
2. A printed image that looks best turned at each seam or join–for example, the note on wallpaper will often suggest that each cut is reversed so that there is no possibility of repeated pattern.
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.
