And a lot of patience.
Step 1: Lasercut the Leather
Put your piece of leather into the Laser Cutter and load the attached Files into your favorite Vector Graphics program. I designed them in Adobe Illustrator, but you can use your favorite tool.
Please make sure that you laser all lines as hair-lines (0,0001 pt) so your laser cutter cuts the leader instead of engraving.
If you engrave things like the Logo, first engrave, then cut the drawing.
The power / speed / frequency settings of the laser cutter need to be set accordingly the manual of your cutter because it depends on the Watt of the device.
Step 2: Sew the Zip
Take the cut out pieces (the front and back side of the bag) to the shoe repairman and let him/her sew the zip with his sewing machine onto the Bag.*
Please make sure that on the top side of the bag zip you leave 4 centimeters on both left and right side of the zip, so that you can make the nice end-piece.
* If you have a sewing machine which can sew leather you can also do this yourself.
Step 3: Sew the Mosaic Tiles
Take a needle and the string and sew the mosaic tiles so they fit into the front window.
Make sure that you sew them from the back and you sew them in a 45 degree angle.
Step 4: Sew the Bags Components and Sew Them Onto the Bag
Sew the rest of the components onto the bag as shown in the picture.
All big holes need to be hammered with a double-cap-rivet - as shown in the picture to make the leather stronger.
The handle also has 2 double-cap-rivets and is sewed so that you don't see the fissure.
The latches on the front bags need to be applied and the front bags need to be sewed onto the bag - take the small needle for this because on the mosaic there are no pre-cut holes.
Step 5: The Inside of the Bag
Take an old Jeans and cut away the legs.
Invert the jean so that you can put it into the bag and be able to access it's bags. Sew together the holes where the legs where.
For the LED Light sew the Battery, on/off-switch, push button and all LEDs on the jeans so they light up the inner side of the bag according the diagram.
