@sims If they are stapled skeins I first look on my discontinued spreadsheet.
Solid – Discontinued Amethyst
Variegated – Discontinued Blue Violet
Variegated – Discontinued Plum
Discontinued (or renamed/reformulated) when Vikki changed to the new dyes. (You may run across Dragon Breath & Dragon Breath II)
