From late 1990s [useful for matching colors used in older knitting patterns].
Shades for 2-ply jumper weight, 2-ply lace weight, 1-ply Cobweb, 3-ply Yarn, 2-Ply Soft Spun, Embo 3-ply, and Unst Fleece 4-ply yarns.
The samples for the 2-ply jumper weight were cut apart, to make them easier to compare to other shade cards, but all colors are included and intact.
