I saw this suggested on another thread, but there is no magnified view to get a closer look.

I am just starting out on GTD and my work habits tell me the 43 folders concept may be most useful. If I can't find a readymade product, what is the best way to make my own from stationery supplies?

Apologies if this question has been answered already. I have been through some of the replies but couldn't understand them well enough.
