when i purchase wool jackets to use from thrift stores/yard sales i take them apart- remove buttons- what ever take the linings out- then wash them in hot water- and detergent-rinse in cold water then dry in a hot dryer- then it is ready to use for what ever i'm going to use it for- wool appliques- patchwork- hooked rugs, purses- what ever i am using it for-
you can also over-dye your wools in you want.
