Pad Making Instructions
Base + insert pads
I just sewed these up quickly, but basically its a PUL (waterproof fabric) pad shape, with either pockets at each end, or straps (I used thin elastic as I had nothing else at hand, but something a bit wider might be better), that hold the absorbent pads in place (You could use twill tape, rick rack, ribbon or even snaps if you wish). This way they can be supplied with 1-3 bases (basically a one on, one washed and drying and a spare) and several absorbent inserts.
Exposed PUL is useful for being completely wipe clean - so the one base can be used all day, but If you are concerned about the PUL touching the skin being irritating, you could top the base in something like microfleece or polarfleece, however this will stop it being so wipe clean, (an absorbent top fabric would make the base soiled and not be able to be reused again so wouldn't be recommended). The inserts will cover most of the PUL, the only part touching skin should be the wings on the top of the thigh. If you wish, you can make winged inserts, but you will have to develop a pattern for those.
As PUL (a waterproof fabric used in cloth pad and diaper/nappy making) is reasonably expensive, this option means that you would need to only provide 2-3 waterproofed pieces per set , however if making AIO pads, each pad should be waterprofed, so that means more waterproofing is needed.
