There's a whole sub to check out: r/clothpads

You could try supporting Etsy sellers, many people have gotten theirs through people who make them themselves!

Here's a handy site which is useful to anyone interested in cloth pads, not just making them: https://clothpads.wordpress.com

I bought thicker, fleece-like reusable pads before, I didn’t like them because I felt they were too bulky and held the heat/moisture in in the summer. I now use cotton, breathable pads by THINKCO: https://www.amazon.com/THINKECO-Organic-Reusable-Menstrual-Sanitary/dp/B071GKWPT8/ref=sr_1_16?keywords=reusable+menstrual+pads+100%25+cotton&qid=1558199515&s=gateway&sr=8-16

For laundry, some people can just fold them up and wait for laundry day, but I found mine stain. Not the worst thing in the world, they are going to stain, but I like to keep them looking clean. Someone told me to put them in a bucket to soak in-between washes. so that is what I do. Usually scrub them by hand together against themselves.
