I have an assortment of pads in all different sizes, and also a few different materials. I have pantyliners, regular size/flow, heavy, and overnight/postpartum. I even have a few postpartum pads with pockets for a handy dandy ice pack. That was heaven after the birth of my 4th baby.
I also have a Rubbermaid container that I keep them in underneath the upstairs bathroom sink. It keeps everything nice and neat, and protected from the elements. It fits perfectly in the cupboard too, so they're out of site from anybody who may wander up there.
I'm sure you're asking yourself "What the hell does she do with the dirty ones?". Well...I went and purchased a small 2 gallon sized flip top trashcan and a wet bag made for cloth diaper use. I use the wet bag to line the trashcan, and keep it next to the toilet. I also throw a little baking soda in the bottom to help absorb odors. I would upload a pic, but my camera has decided to only send certain pictures.
When I remove a pad, I put it in the trash can. If it is heavily soiled, I rinse it first with cold water. At the end of the day, they all get thrown in the wash and washed on hot with no fabric softener. If you cloth diaper, you could wash them with your diapers if you want. If it's just pantyliners from every day use, they get put in with the whites.
Any questions? This may very well be the least "gross" crunchblog, so I wanted to get it out of the way. ;)
