Rolling Texture

Hi

I make the occasional braid on a Japanese loom called a Maru Dai. I
would like to try to run some through the rolling mill to put
texture on fine (or sterling) silver…don’t know yet. If they are
small braids, say 2 to 4 mm in diameter, will they damage my rollers
if I properly sandwich them between the sheet silver and a piece of
brass sheet?

Thanks
