I wash and reuse my flushable liners that have only been weed on all the time

(and this is really embarrassing.... shhhh.... and I iron them so they are nice and flat again.... don't tell anyone.... I don't even iron DH's business shirts for work but I iron disposable nappy liners)
OMG literally LOL!!!!!! that's so cute

You could easily make some out of microfleece. You can just cut them out and it won't fray. Soooo cheap. But yes I have some flushable ones that I have washed many times. They don't travel well in the dryer tho hehe!
