"Four lines of warp-thread are then fixed from end to end of the roller, two above and two below the groove."
"When two of the warp-thread courses are complete, insert either the pointed end of the bobbin or a blunt needle between the warp-threads below the woven portion, and if necessary move the warp-strings a little to or fro until they are equally separated each from the other all along the line."
"Now weave two courses with this warp-thread and beat it down with the comb, leaving the woof during the process rather loose."
