1. MAKE THE PATTERN
Make the pattern for the bag. 
2. CUT THE LEATHER
Cut the leather following your template. 
3. DRAW THE SEAM LINE
Then draw the seam line, doubled with a decorative line. 
4. WORK ON SEWING
- Chamfer the edges with a beveler.
- Use a stitch to cover the seam, that is, to make it invisible.

5. TINTING THE LEATHER
Dye the grain side of the leather with a Fiebing's dye, in this case Fiebing's Black Oil Dye. The reverse side will be dyed with USMC Black - Leather DYE (also from Fiebing's), the result on the crust side being more uncertain given that it is not designed to be dyed.
GUIDE: HOW TO DYE LEATHER?
6. ASSEMBLE THE PARTS
After the various elements have dried, it's time to assemble them. Sewing and riveting the mounting panel (the piece of leather that will be screwed onto the motorcycle) to the rest of the bag.

7. MARK THE STITCHES WITH A ROULETTE
- First, mark the stitching points with the roulette wheel.
- Drill with a diamond/rhombus awl all the holes for small parts, and every other one for larger things. For this bag it will be all the holes (4mm).
8. CUT AND TINTE THE STRIPS
- Cut the straps for 20 mm chrome buckles.
- Dye the straps with Fiebing's dye.
9. ASSEMBLE THE STRAPS AND LOOPS
- Join the 2 straps together using rivets.
- Assemble the 2 loops with staples or by sewing.

10. GLUE AND SEW THE SIDES
- Make a collage.
- Sew the sides to the main panel (saddle stitch).

You can also choose to make a corner seam (be careful to adapt your templates correctly).
CORNER SEAM - SEE THE COMPLETE GUIDE >
11. PLACE THE STRAPS
Install the strips by riveting. This can be done before assembling the sides for ease. 
12. TOUCH UP THE DRAPES AND FINISH
There are still some small finishing touches to be done: touch-ups of dye and finishing of the edges with beeswax.
