You will need:
Two pocket squares - each 8" square with a pocket in the middle.
Four denim strips 8" x 4"
Four denim strips 15"x4"
One denim strip 4"x16"
Two lining pieces 15" square for inner bag.
Two lining pieces 4"x6" for fastening flap.
Two lining pieces 15"x8" for inner pocket.
One lining piece 4"x16"
One lining piece 6" wide cut the entire width of the fabric (for strap).
One lining piece 4"x6" for key tab.
One lining piece 2"x36" for binding
Take the 4"x16" strips. Fold in half lengthwise. Mark the centre of the short side and mark 4" down from this on the long side. Use a cutter and ruler to cut a straight line between the two points.
Join the 8" x 4" denim strips to the sides of each of the pocket pieces.
Take the pocket pieces. Place them under the body lining and cut the curves to match.
Pin the pocket linings right sides together and stitch along the top edge.
Fold the keytab in half and put a split ring in the loop. Pin this to the edge of a bag piece about 2" from the top.
Add the fastener to one of your flap pieces and to the main bag. I used magnetic catches.
Turn the bag right side out. Place the lining inside the bag, wrong sides together. Pin the straps in place at the sides of the bag, centring over the seam. Pin the fastening flap in place. Put the binding against the top edge and stitch all the way round, starting 2" in. As you get to the end, fold these two inches of binding back and stitch the final end over. Fold over the top of the bag and slip stitch in place.
