[Cadillac Forge]

i have been searching the web high and low trying to obtain a basic knowlege on how to
create the spider web effect in mosaic slices, several makers seem to produce this pattern
i understand everything about this process except the the pattern, can anyone give me a hint, or give me a link or suggest a book or something? seems to be very little on the net
covering the process of can damascus, i know ed caffrey is coming out with a tape in the future and looking forward to it thanks for any advice bruce
