and how many times did you run them through the washer and dryer before using them? The heat from the dryer seals the PUL around the sewn holes. I have some that I made (from diaperkits.com actually!

) that were leaking when I first made them and I thought it was the PUL, but it was actually just me.

After about 3-4 uses (running them through a normal cloth diaper cold hot cold wash and full drying cycle) they stopped leaking and have been fine for months ever since.
