Place the pattern on a double layer of fabric. I used a home decor weight so did not interface it. If you use a lighter weight fabric I would recommend using an iron on interfacing to give stiffness.There is a flickr group for the lush shoulder bag....if you make a bag from my tutorial please add pictures to the group pool...I would love to see your bag.
Here you can see the measurements if you click on the picture to enlarge.
Cut out lining...again on a double layer.I used fleece fabric for a soft finish.
This is the pattern for the pocket,cut two pieces.I used co-ordinating fabrics.
Pin the outside marks to the centre to form a pleat on both fabrics.
Pin the two pieces together ,sew around leaving a gap at the bottom to turn out.
trim the corners.
Sew the 2 sides on the lining.
Sew one side of the main fabric.
If you like add a trim to the top of the pocket.I could not resist this pretty ribbon.
Open out the main fabric and place the pocket centrally on the seam you sewed.Sew the pocket in position.
Sew together the other side seam.
Open out the bag so that the two seams are on top of one another and sew along the bottom edge of the bag.Do the same with the lining.
Make corners and trim excess.Again do this for the lining too.
This picture might give you a better idea of how to do the corners.
Next is the button flap.Cut two pieces 5inches by 3 inches.
Sew around 3 sides and clip corners
Overstitch and sew a butonhole.
Place the lining into the main bag right sides together.
Place the botton flap between the layers centering it on the middle seam.
Pin the two layers together all around,keping seams and corners matched.
Starting about 5 inches from the end of the strap sew down along the strap ,across the front of the bag and up the second strap,taking care at the corners.
Stop about 5 inches from the end of the strap.
Sew the other side from beginning of the strap to the end of the other side.
