I have had success with socks,
the single ones that are left over when your dryer eats one of the pair
you can stuff them with toilet paper and you can adjust the length for a custom fit.
they can be a little bulky, they work well at night.
I also have had success with natural sea sponges, they can be squeezed out on your favorite plant or in a container to be added to your compost
when rinsing out in a public washroom I had a woman express concern about my bleeding hand.
They can be bought at health food stores, look for denser firmer ones, they can also be customized.
