A simple wet bag for diapers takes only minutes to complete.  No measurements are included on this because you can make it as big or as little as you like.  Small enough for your breast pads or momma pads, or large enough for several diapers in your diaper bags.  A closure isn't required, but you can add a quick strip of velcro with a zig zag stitch, or a few snaps to hold it closed.  I make these from scraps too small for diapers!  Use these tips if you haven't sewn with PUL before.

1.  Make a large rectangle from your fabric.

2.  Fold over the short ends once, sew a straight stitch, then fold over again.  Stitch another straigth stitch close to the edge.

3.  With the right sides facing together, fold the two ends so they overlap.  The side that will be the top flap should be on the bottom.  Overlap approximately 2".

4.  Pin the overlaps so they don't move around, and stitch closed the sides.  I do a quick zig zag stitch to secure the edges, but it is probably not necessary.  Turn right side in and you're DONE!
