Okay, here's the tutorial at last, I apologize ahead of time for the fact that my photos are a little fuzzy. This is for the bag I posted previously that was based on a Japanese bag my coworker showed me. It is basically a lined zipper pouch with a lapped zipper pocket added on one side, and a "handwarmer" pocket on the other side...here are the pieces you start with:
The pieces are grouped together...the top right hand side is the main zipper and bag lining, the lower right side is the handwarmer pocket pieces, and the left side ones are for the lapped zipper pocket(that's just the zipper laying across it!). Start with the bag lining and main zipper...
The first step is to attach the right side of the fabric to the wrong side of the zipper:


This is how it should look...zipper wrong side up and fabric right side showing.
Then you begin piecing together the pockets. Handwarmer pocket first. Take the outside and inside of the outer part of the pocket...face the wrong sides together so the "good" side of the fab. shows out on both sides. Topstitch along the diagonal edge to attach them to each other. Then attach this piece to the pocket lining by stitching along the top, within the seam allowance:


Next, work on the lapped zipper pocket. Cut room for the zipper in the outside piece and the backing for the outside piece--and iron the seams back:

Attach the zipper...you can do this with or without lapping the zipper, just make sure to leave enough fabric for lapping if you go that route.... The outside of the pocket will attach to the front of the zipper and the backing will attach to the back of the zipper. Sew that zipper on.

Place this piece on top of the pocket back and sew across the top as with the previous pocket, within the seam allowance, to hold them together.
You now have three pieces:

Iron seams across the tops of the pocket pieces. Pin the tops of the pocket pieces onto the zipper:

Then fold the pocket pieces back on each other, so that they lay inside out on one side of the zipper, and the lining of the bag lays on the other side:

Sew around the outside of the pocket pieces. Sew down the sides of the lining also...but DO NOT SEW THE BOTTOM OF THE LINING YET!!!
Turn it all right side out. You should have something resembling a purse at this point, with pins going around the top. Stick the handle in under the pins (I had this handle left from another project, sorry no construction photo!):

Sew around the top! Ironing or hammering the seam all the way around may help if your machine doesn't want to sew through all those layers (take it from someone who broke a machine by not doing that...) .
Then you gotta pull the lining out and close it. I like to iron the seams under and just sew along the bottom, as close as I can get it to the edge:
