No replies to this thread. This is unusual for the thriving and frequently updated batik forum!
Is it because: - I have asked something very obvious - I have asked something that people would not find useful. (Surely not!) - This is already been worked on - This is an incredibly good idea and someone is going to patent it!? - People are too busy I'd like to help with a solution; from my posting history you'll see that I try to post answers to my own problems and also help others. In general thanks for all your support!
