Nice... It worked w/ rendered images: I turned them into JPEG and posted... Right... here's what I want:

All of those grey tinny lines are my strings. I duplicated them but I want the size of each one to fit the brown box. Was wondering if there is a way to duplicate with the sizes correctly - maybe using a curve as reference - or I should resize each one of them after duplicating?

Hope it's more clear...

thx
