My mom had a great idea, when I had my oldest son, to use plastic diaper covers in my nursing pads.
Nothing else had ever worked because I don't just leak - I spray :o) I made 8 or 10 pairs, but after 3 years of nursing my first 2 boys, I definitely needed a few new pairs for the third time around.
One large cup (or whatever size seems best - and cleanliness is optional,
as you can see from the coffee stains :o) )
Old cloth diapers, or any soft, absorbent material
Plastic diaper cover (can substitute wool, fleece, or other water-resistant materials)
I used 8 layers total (4 on each side), of a very thin cotton diaper.
Depending on the type of material used,
adjust the amount of layers for desired absorbency. One layer of plastic in the middle.
I got 5 pairs out of one 12-month size vinyl diaper cover.
I used a very large coffee mug (4 inches diameter), giving me enough room to sew and trim,
with the finished product being 3 1/2 inches, give or take. I used a straight stitch and then
trimmed it really close.
I set my machine to the tightest zig-zag to finish the edges.
Finished product! No more leaky shirts!
