Washing your Kyrgies slippers
Kyrgies do not like to get wet. Like wool sweaters, they will shrink and become misshapen. The magic of wool felt is that it wicks moisture and shouldn't ever smell. If you do spill motor oil or bacon grease all over your Kyrgies, you can save them by getting them dry cleaned.
Just do not wash Kyrgies with water. It will change your Kyrgies and they will be rendered unwearable.
Wash your peshtemals in cold or medium warm water, on a gentle cycle, with similar colors. Don't use bleach or fabric softener. Dry on low to medium heat.
