All the information i am providing you with came from the website below. If you need further instructions or i am not explaining my self well. I will also be using there pattern, that you can also download off her website or from this page.
Step 1: Materials
Fabric (Flannel, Cotton, bamboo. I personally used some of my extra swaddling blankets. I received to many at my baby shower. Its breathable and sokes stuff up.)
IMPORTANT! It might seam tempting to use water proof lining on your breast pads. But using a water proof lining can cause what is called clogged ducts. Your nipples is still skin and need to breath and lactate. If they don't what will happen is one of the holes in your nipple can become clogged. That one duct will get engorged then your breast it will be uncomfortable and possibly painful. IMPORTANT!
Step 2: Cut out your peices
Because of the way i folded the swaddling blanket for my cuts i had to make 3 pairs of breast pads.
You don't have to make 3 sets but this will be nice so you don't have to worry about washing clothes everyday.
