I made a simple and pretty little bag. I used a machine, but hand sewing is enough so let's take it step by step.
Step 1: Design&Sketch
Imagine and sketch the final image.
Step 2: Make a Pattern
When I cut a circle, I used a special tool. This is called the Circle Cutter.
Step 3: Bond the Bottom
Provides full bonding to ensure floor strength
Step 4: Sew the Bottom and the Sides of the Bottom
Sew the leather and the thin side strip
Step 5: Combine Body Parts
Combine both sides with the inside facing outward.
Step 6: Turn Over
Turn over inside out
Step 7: Sew the Bottom and Body
Fold the top part and sew the bottom just in time.
Step 8: Make a Lining
Use patterns to create lining
make a little smaller than leather
Step 9: Make a Short Strap
Bond the whole thing and fold it
Step 10: Make a Long Strap
Bond the whole thing and fold it and sew it.
Step 11: Sew the Strap and Body
The tips join the body through hand sewing.
Step 12: Combine Metal Ring and Strap
Sewing the ends only and joining the center with rivets.
