Cut out all your PUL pieces (including snap-backing).
Apply your rise and front panel snaps (or rise snaps and front loop strip for hook and loop).
Fold in the edge along the leg elastic areas and sew your casings (I use 3/8", but CB uses 1/4").
Leg elastic casings sewn.
Lay out your tucking pocket pieces face to face with the laminated sides out.
Trim up your edges and turn the pockets.
Top-stitch around your pockets.
Sew your back elastic casing.
Install your elastics (the casings are all open and easy to thread through).
Stretch to desired tension and tack+trim.
Now just apply your wing snaps.
Full rise and larger waist snap setting:
And I guess, with their new Elemental being just like a Flip with the sewn-in soakers, you could easily use this to make your own faux Elementals (or easily convert Flips INTO Elementals) just by adding the SOAKER...
I was asked how I stitched the soaker into the body with no seams showing. I just turned the cover inside-out with the pockets flipped so the shiny side of the PUL was showing, and then serged (but you could sew regularly as well) the very edges of the pocket flaps to the edges of the soaker. :)
