Is there any kedusha in a yarmulke after it has been worn? Do I have to put it into shaimus or can i just throw it out? Thank you.
There is no kedusha in a yarmulke, and it can be discarded in the regular manner.
Although one should not throw out mitzvah items in the garbage, a yarmulke is not a mitzvah item, and although it represents an important custom, it does not have kedushah and can be thrown out after it wears out.
