FULL TUTORIAL VIDEO
1. TRANSFER THE PATTERN ONTO THE LEATHER
Using a silver pencil, trace the pattern pieces onto the leather and lining. Also mark the position of the various holes.
2. CUT OUT THE DIFFERENT PIECES
Cut out the different pieces of leather and lining with a cutter or a pair of scissors.
 |
 |
To reinforce the leather, glue a piece of tear-resistant tape (or a small piece of leather) to the holes. Drill the various holes with a 3 mm round punch on the leather.
3. PREPARE THE DIFFERENT PARTS
Place double-sided tape on the three sides of piece P1(b), on the reverse side of the leather (see diagram).
 |
 |
On this same piece P1(b), work the edges with an edge finish. The edges are worked with an edge finish/paint. You need to apply 2 to 3 coats of finish. For more information, we invite you to consult the guide below.
Also work the edges of the 2 small widths of one of the P2 pieces (facing). Place double-sided tape on the 4 sides of this same P2 piece which has the painted edges. And on the two lengths of the second P2 piece.
4. PREPARE THE STRAP
Cut 72 cm from the leather strap.
Transfer the pattern from piece P3 onto the strap. To make the oblong hole (the sash), make two Ø 3 mm holes spaced 2 cm apart and join them with a cutter to hollow out the central part.
On the other end, work the tip into a point. The 4 slotted holes will be drilled in step 11.
From the leftover strip, cut another 15 cm piece to make the handle (if the leather is soft, don't hesitate to double the handle or use sugherite - Ref ) . Transfer the pattern from part P4: cut the ends to a point and make the Ø 3 mm holes in the locations provided on the pattern.
 |
 |
Work the slices of the two strips P3 and P4.
 |
 |
5. ASSEMBLE PIECE P1
Assemble the bottom of the P1 pieces by overlapping the P1(b) piece by 1 cm on the P1(a) piece, wrong sides together. Then, sew 2 mm from the edge.
 |
 |
Screw the collar button onto the last hole of the P3 strap.
Insert the loop into the loop of the strap.
Then, using double-sided tape, glue the strap P3 to the location provided on the part P1 of the collar button P1(b) to the rivet P1(a).
Drill the strap and part P1(a) at the same time for the rivet hole.
Attach the strap to the main piece by placing the rivets in the two locations provided on the pattern.
 |
 |
Stitch the strap in two steps (to avoid having to stitch the bottom seam and to avoid excess thickness). Sew about 2 cm from the rivet and the collar button.
 |
 |
Fix the handle P4 with rivets on the part P1(a), in the location provided on the pattern.
Sew the two sides of pieces P1 together, wrong sides together (always piece P1(b) on piece P1(a)).
Turn the bag inside out and sew the two corners right sides together.
 |
 |
6. ASSEMBLE THE FACING
Assemble the facing with the double-sided piece P2 with the painted edges (worked in step 3). Glue this piece to the ends of the other piece P2. Glue the wrong side together about 1 cm apart. Then, sew the two ends 2 mm from the edge.
 |
 |
7. ASSEMBLE THE LINING
Join the two P5 lining pieces together, right sides together. Sew only the bottom and the 2 sides.
Then, sew the corners right sides together.
 |
 |
8. ATTACH THE LINING TO THE FACING
Glue the right side of the P5 lining to the wrong side of the P2 facing, 1 cm from the edge. Be careful to match the seams.
Sew the facing to the lining 5 mm from the edge.
9. SEW THE LINING INTO THE BAG
Insert the lining inside the bag. Glue the facing to the top of the bag with double-sided tape (wrong side against wrong side). Stagger the middles to avoid excess thickness.
 |
 |
Sew all the way around the top of the bag, 5 mm from the edge.
 |
 |
10. FASTENING THE SNAPS
Re-drill the snap fastener holes to pierce the facing. Attach the three snap fasteners. Pay attention to the direction of the snap fasteners:
- For the middle button, attach the two parts towards the inside of the bag.
- For the buttons on both ends, attach both parts to the outside of the bag.
 |
 |
 |
 |
11. DRILL THE STRAP HOLES
Make the 4 adjustment holes at the end of the P3 strap. Make a small 3 mm notch above the holes to allow the collar button to pass through.
 |
 |
12. WORK THE TOP SLICES
Work the top slices of the bag with a slice dye.
You're done!
