Cotton Roving by Hand: Carded, Drawn and Lightly Twisted
Roving is cotton made ready to spin: the fibres combed parallel, drawn into a long strand and given just enough twist to hold together. Mills did it with carding engines, drawing frames and roving frames; Andrew Ure (1839) explains them by the hand cards they copied. This is the hand version, from ginned lint.

Double, draw and add a little twist
Lay two or three slivers together and draw them out to the length of one; repeat a few times to even out thick and thin places, as the mills' drawing frames did. Draw the strand to about pencil thickness. It now pulls apart easily, so give it a little twist with a slowly turning spindle and wind it on loosely. That twist is what makes it roving.
