Erin, I had to laught at "do you wear one at a time"
The pads I use come in there different styles
1) Day Pad: A day pad has two cloth inserts that you can add as needed for heavy flow days. This pad is a normal size that can be worn somewhat discretely (but I would not advise wearing spandex
2) Night Pad: These are HUGE LOL! They have 2 inserts, and the length is at least a third longer and wider then a day pad. They work great for night and for postpartum, but they aren't sexy! LOL They get the job done
3) PantyLiner: No inserts here. Very thin, but provides protection on those days when you are very light, or just unsure!
Now, after you change a pad, you can put it in a clay pot or ice bucket in your bathroom. It will be filled with cold water. This will keep the stains from setting. I wouldn't leave them in there for more then 3 days, so try to get them in the wash within 3 days. I use BacOut to prevent stains etc. It works wonderfully, but I've been told that you won't get stains if you soak in cold water first, so that may be overkill.
They snap around the bottom of your panties, making them a secure fit, and they feel so much nicer on your skin! I use the hemp fleece ones, and I really like them. I do have one wahm style made of flannel that is ok, but not as absorbant as teh hemp fleece.
(one thing about hemp fleece, though...it needs to be washed on very hot water several times before using to break down the natural oils in the fibers and make it absorbant).
So, that's my explanation. Does it help?
Wanna see what they look like?
