Those websites are unnecessarily complicated. I wore washable pads that I sewed myself for five years, and as soon as we are settled I'm going back to it.
You don't need all the "envelopes" and complicated pockets, you really don't.
Take an old towel (or two) and an old waterproof baby pad, the kind that looks like felt. Take your favorite menstrual pad and use that as a pattern. Cut as many of that shape as you can out of the towels and pad, about 3 towel pieces for every waterproof pad piece. Sandwich three towel pieces with a waterproof piece on the bottom, and blanket stitch around the edges. If you're any size over about a 6, the pressure of your inner thighs will keep the pad in place in your panties with no fasteners. If you want to get really really fancy, cut the waterproof layer with "wings" large enough to overlap on the underside and add a snap.

Easy as pie.
