there are probably still sites that sell diaper liners .. these go
into the diapers and you pull and toss in toliet .. then wash the
diaper ..
looks like the holey washclothes that they sell in packages (18-21 yrs
ago) .. in the old days (40 yrs ago) they were sorta ‘papery like’
with a film on them ..
I did cloth for a long long time LOL
I did a quick search and they have different stuff today
