A wool-pack, as its name implies, is a sack in which wool is packed and bundled; the packs were of standardized sizes, for ease of pricing. It was used as a charge by the Worshipful Company of Woolmen as early as 1575 [Bromley & Child 267]. It may also be called a “bale” or a “wool-sack”; it is fesswise by default. For related charges, see bag of madder, cushion.
