Boostable pads are a pad, that can have a booster placed under it to increase the absorbency. This also allows you to use a waterproofed booster on days you need to, and not use it on days you don’t… or have a thin pad that you can increase the absorbency of.
One type of boostable pad is made by cutting out a pad shape (here I’ve used a layer of printed flannelette/flannel and a layer of hemp fleece), and then cut a strip of fabric (can be PUL as in this example or something else like fleece, flannel or cotton). Edge the long sides of the strip, and then pin it in place
Then you can sew it up (here I’ve overlocked/Serged the edges, because that’s easiest)
If you like the contoured shape you can get with a wingless pad, but also like to have wings to hold the pad in place,… you can make a separate wing and sew it to the back of the wingless pad.
To do this, lay the pad down ontop of the wing (or put the wing on the pad) – making sure the centre point of the wing is in the centre point of the pad (or your wings will be off centre), pin it in the right position, then sew down each side. This will create a little pocket/sleeve part – where you haven’t sewn the wing on at the top or bottom, so you can add a booster.

You can then make boosters (eg 2 layers bamboo/hemp fleece) and slip one of those into the back of the pad. You could make waterproofed boosters too. The pad will have the hourglass contoured shape that you might not be able to achieve with wings sewn with the pad.

Another option for a boostable pad is to make a normal non-waterproofed pad, but before sewing it all up, put a snap on the underside of the pad (so that once it’s sewn up, you don’t can’t see the top of the snap), and make boosters to snap onto the underneath.
