“dyed-in-the-wool”

• died in the wool → dyed-in-the-wool See the fix →

From cloth-making: wool dyed before being spun holds color deeper and more permanently than fabric dyed afterwards. A 'dyed-in-the-wool' belief is thoroughly ingrained. 'Died in the wool' would just be a sad sheep.

DYED, not DIED. The image is colorfast wool, not dead wool.
