To start you need to decide what size you want it and create your pattern peices.
You want a front and a back,
two side
two top (a zipper seem alowance larger than the bottom
a bottom
a strap
Then you want all that agian in a lining fabric plus what pockets you want to use.
I didn't get a shot of the lining.
If you want to decorate the bag do it now.
I had to redo over the zigzags that hold that fabric bit on like four times by the end.
The first thing we are going to do is put the zipper in.
pin the right side of the fabric to the wrong side of the zipper and sew down the edge. LEAVE A SEEM ALOWANCE AT THE ENDS
fold it over and sew down the edge again so its flat. LEAVE A SEEM ALOWANCE AT THE ENDS
Do the same thing for the other side.
For the outer fabric put it right sides together and sew down the side with a seem alowance large endough to put a zipper in. Then sortof flatten it out.
Then lay it so the seem is over the zipper and sew down either side. LEAVE A SEEM ALOWANCE AT THE ENDS. Unpick the stitches going down the middle (or you could leave the stitches in untill the end and it would probibly make attaching the top to the sides easier)
Make your straps (sorry I didn't get a photo) sew them to the sides. Sew all the side peices together. LEAVE A SEEM ALOWANCE AT THE ENDS
Sew the bottom to the bottom leaving a great big hole. you are going to be turning things insideout through this.
Trim the corners.
Sew the top to the top being carefull not to sew through the lining fabric (wich is easy because you left a seem alowance)
Trim the corners.
Make your pockets for your lining. I chose to make elastic pockets.
Sew up your lining the same way, but sew it with larger seem alowances because your lining has to be a little smaller than your outer fabric. And leave an even larger hole in the bottom, you are going to use this to sew closed the hole in the bottom of the outer fabric.
Trim back your seem alowances.
Turn right side out by reaching in the inner bag, grabbing the zip, then pulling.
Sew closed the hole in the bottom of the outer by pulling it through the hole in the lining and sewing from the inside.
Sew closed the lining.
YOU ARE SO DAMN DONE!
