Ok..I have finally looked it up and they look REALLY easy to make
I found this patern easier because itīs made with things I have around the house.You will need one of those impermeable matress protector sheets (one made for a single bed will make 4 to 5 good sized pads) for the bottom of the pad,some towels (for the middle) and some pretty cotton fabric fot the top layer.
Basiclly you sew the 3 layers together and thatīs that
Make sure the bottom layer (the matress protector) has the plastic part facing down (the floor) and the fuzzy part facing inwards,because the extra material on the inside will make the whole pad that much more absorbant
Iīm going to make mine this afternoon and see how it goes.I hope this has helped!
