THE NECESSARY MATERIALS
- 2 pieces of leather (different) 20 x 30 cm - 0.5 mm thick
- 4 mini snap fasteners – Nickel-plated – diameter 10.5 mm
- Manual press pliers and setting set for setting mini press studs
- 2mm and 4mm cookie cutters
- 2 sliding buckles – Nickel-plated – 16 x 10 mm
- 2 half-round rings – NICKEL-PLATED – 14 x 12 x 2.2 mm
- Black tear-resistant adhesive tape
- 1 silver pencil
- 1 metal ruler or rule
- 1 cutting mat
- 1 cutter and scissors
- Fabric (for the neckband) at least 10 x 65 cm
- As well as a sewing machine and polyester thread.
1. CUT OUT THE 4 PIECES (FOR EACH KNOT – FATHER & SON)
Using the silver pencil, trace the pieces onto the leather.
Cut out the rectangles using a ruler and a cutter (or a pair of scissors).
Piece No. 1 (largest knot) -> 1 time (leather 1)
Piece no. 2 (smallest knot) => 1 time (leather 2)
Piece n°3 (loop of the knot) => 1 time (leather 2)
Part No. 4 (fabric neck warmer) => 1 time
The pencil is erasable on most leathers with a simple eraser (do not use on vegetable tanned leather). We recommend that you test it first to confirm the erasability on your leather. 
2. REINFORCE THE KNOT LOOPS WITH TEAR-PROOF TAPE
Place tear-proof tape on the leather crust of the knot loop (part no. 3). 
3. SEW PIECES NO. 2 AND 3 (FATHER AND SON)
Fold pieces 2 (small knot) and 3 (knot loop) in 2 (lengthwise) and sew the top edge on the right side. 
4. MOVE THE SEAM TO THE CENTER
Move the seam to the center for pieces #2 (small knot) and #3 (knot loop). 
5. SEW PIECE NO. 2 (SMALL BOW) ACROSS THE WIDTH
Fold pieces no. 2 (small knot) in 2 (widthwise) and sew the top edge (on the same side as the previous seam).
Move the seam to the middle and turn the knot over (photo #3). 
6. SEW THE ENDS OF THE KNOT LOOP.
Sew the ends of piece #3 (passing through the knot) on the same side as the previous seam. 
7. SEW PIECE NO. 1 (LARGE KNOT)
- Follow the same steps as for part #2 (small knot).
- Fold pieces no. 1 (large bow) in 2 (lengthwise) and sew the top edge on the right side.
- Move the seam to the center.
- Fold pieces no. 1 (large knot) in 2 (widthwise) and sew the top edge (on the same side as the previous seam).
- Move the seam to the middle and turn the leather bow tie inside out (photo #3).
8. SEW PIECE NO. 4 ON THE WRONG SIDE
- Fold pieces #4 (neckband) in half (lengthwise) and sew on the wrong side. Do not topstitch at the end to make it easier to turn the piece inside out.
- Turn the piece over to make the seam disappear.
- Place the seam in the middle.
9. SEW THE ENDS OF PIECE NO. 4
- At the ends: turn the fabric over on itself (photo no. 1)
- Pass the sliding loop (photo n°2)
- Fold the end of the neckband (the side where the topstitching has not been done) over itself (photo no. 3) and sew it.
- Sew the other end.
10. MAKE THE NECK STRAPS ADJUSTABLE
- Pass the half-round ring (photo no. 1)
- Then pass the end of the neck strap through the sliding loop (photo no. 2 and 3)
11. MAKE THE HOLES FOR THE SNAP BUTTONS AND INSTALL THEM
Make the holes for the snap fasteners (4mm for the head and 2mm for the foot) on the neck straps and the loops of the bows.
