The way I look at it is that since the Hattersley looms are man-powered, as opposed to fully mechanized, the average person will consider the cloth to be "hand woven" because a human being actually had to operate the loom. Whereas a true hand weaver, such as Peter, will look on the cloth in a different light, because an actual hand loom was not used.

In much the same way that a person who makes their own clothing at home, as opposed to purchasing it ready made from the store, may consider their wardrobe to be "hand made" despite the fact that they used a sewing machine. Someone who actually hand stitches their clothing will look on those items as "machine stitched" and therefore not "hand sewn."

In other words, a true hand weaver will have a stricter definition of what "hand woven" means, which would exclude the Harris Tweed cloth production means.
