It's arrived! There was a special delivery this morning and I've been pouring over this most excellent book ever since... Repeat Patterns - a Manual for Designers, Artists and Architects. If you are at all interested in pattern-making in design, I thoroughly recommend it.
One of the things I've discovered while bumbling my way through screen print designs etc, is that I am visual in my design process; I need to see it before me in order to play with the design or judge whether it works or not. This had led to some pretty disastrous experiments as well as some happy accidents.
Repeat Patterns approaches the design process in a very visual way. It actually begins with a school-like tutorial in creating design units that can be positioned for the construction of a repeat pattern. I'm quite smitten :)
