HOW TO SEW LEATHER BY HAND?
VIDEO: SADDLE STITCH TECHNIQUE

1- Glue the leather pieces to be assembled with water-based leather glue - aquagum (in a thread of about 4 mm). Put glue on each piece: contact glue. Do not glue directly, let dry for 5/10 minutes.

2- After assembling the pieces, trace the seam line with a groover, a former or a dry-point compass between 3 and 5 mm from the edge. The seam should not be too close to the edge of the leather.

3- With a mallet and a striking claw: mark the stitching points. The aim is not to pierce the leather entirely but only part of its thickness.

We have chosen to mark the points next to the drawn line in order to keep a decorative line (only possible on vegetable tanned leather) . For beginners, you can mark the points directly on the line.

We recommend using a plastic or polymer hammer to avoid damaging your tools.

4- Cut a linen thread: generally equivalent to 4 or 5 times the length of the sewing line. If you have to do a long seam, take an armful = length with your arms outstretched so as not to have to handle meters of thread.

Waxing the thread with beeswax: pass it 3 times and wipe it dry. It is important to wax the thread before sewing to stick the thread fibers together, protect it and prevent it from knotting.

Thread a needle through each end of the thread:

• Insert the thread at needle height and then insert it twice.
• Crimp the end of the thread and pass it through the eye of the needle.
• Pull the thread to make the knot (see photo).
• Do the same thing to thread the other end of the thread onto the second needle.

You don't have enough thread to finish your sewing? We invite you to watch our video (starting at minute 14) where we explain how to make a connection. Purists will tell you that it is forbidden but it can sometimes be useful!

5- Clamp the leather in the jaws of the saddle clamp / sewing clamp and leave the sewing line approximately 4 mm above the jaws.

6- Pierce the leather with the awl with pliers (diamond awl): raise the elbow to the height of the seam line and form a right angle (90°) with respect to the piece. Be careful, respect the drilling angle with the diamond awl at the risk of not having a beautiful seam.

7- Start sewing with a saddle stitch. Always sew towards yourself.

For aesthetic reasons, in our video we start our sewing at the 4th stitch in order to make 3 double stitches and thus have symmetry in relation to our end seam (the 3 stopping stitches) => to be done only if the seams do not join.

You can also simply start your sewing from the first stitch by leveling the threads or making a saddle stitch (when you are at the edge of a piece - e.g. card holder) .

• Left hand: pass the needle using the iron of the awl (photo no. 1).
• Right hand: form a cross and pull on the needle (photo no. 2).
• Pull the threads towards you to avoid any marriage* and pass the needle (right hand) in front of the thread you have just passed (photo no. 3).
• Take the thread on the left side and pass it over the needle towards the outside: make a comma (photo n°4).

Our advice for beautiful sewing: practice ! The movements must become mechanical.

*Marriage: when one thread enters the other thread (forms a kind of knot): a mixture of threads.

8- Pull on each needle to tighten the stitch : left hand upwards and right hand towards you - diagonally at about 45° to the leather. You must tighten the stitch well (use your thumbs) and have the same tightening force for each stitch.

9- Make 3 stop stitches with a round awl to enlarge the holes: do not make a comma / pass the thread over the needle. Cut the thread flush then put a dot of glue on each side.

10- Hammer the seam with a riveting hammer or a joining hammer: pay attention to the angle of the strike and do not hit too hard so as not to damage/mark the leather.

All you have to do is work the edges with a square cutter then an edge finish or a finishing gum (tokonole / gum tragacanth).

WHICH THREAD AND NEEDLE SHOULD I CHOOSE FOR SEWING LEATHER?

The most commonly used thread diameter for hand sewing leather is:

For leather goods (handbags, school bags, etc.).

• 632 – Chinese Thread
• M50 – Meisi
• Ø 0.55 mm

For small leather goods (card holders, purses, etc.).

• 832 Chinese Wire
• M40 – Meisi
• Ø 0.45 mm

The Deco Cuir needle, with a round tip, reference (L3912) is size 002 - Ø1 mm. You can use this needle for all your "standard" leather goods creations. For small leather goods, choose size 004 - Ø0.8 mm.

THE TOOLS NEEDED FOR SADDLE STITCH SEWING

SADDLE CLAMP
The sewing pliers are essential for sewing leather by hand because they will serve as a third hand to hold the piece of leather. The pliers are positioned between the legs. We advise you to protect the beak of your pliers with self-adhesive leather to prevent the diamond awl from damaging it. We also advise you to have a small 10 cm wedge under your foot in order to have better support for the pliers.

AWLS
The round awl allows you to enlarge the holes without breaking/damaging the thread to help the needles pass through, particularly when starting and finishing sewing.

The pliers awl, also called a diamond awl, is used to pierce the leather before saddle stitching (hand sewing of leather).
Tip: remember to sharpen your awl well to avoid forcing and damaging your leather.

HOW TO SHARPEN AN AWL WITH PLIERS?

To have quality work, you need quality tools. To do this, remember to sharpen and hone your tools regularly!

DRAW THE SEAM LINE
The former, the furnette and the dry point compass are 3 tools which allow you to trace the sewing line: choose the tool which suits you!
The compass is handy for going to the middle of a room and the tree frog can also dig a furrow to drown the thread and protect the seam.

MARK THE STITCHES
The striking claw or the stitch marking wheel allows you to have sewing stitches at regular intervals.

Below is a quick summary of our favorite tools:

We have drawn on our experience to offer you a starter kit with the essential tools for hand sewing leather (3 ranges: Essential, Essential + and Premium).

HOW TO SEW IN A ROUNDED WAY?

The technique is the same for rounded sewing! We invite you to mark your points with a marking wheel which will be the easiest tool to use (or a 2-toothed claw). The drilling angle with your awl with pliers must follow the inclination of the points.

HOW TO SEW AT ANGLE AND WHAT IS DOUBLE-STITCHING?

WHICH LEATHER SHOULD I CHOOSE FOR SADDLE STITCHING?

The ideal is to select a thick leather (at least 1.2 mm thick) and not too soft. We invite you to go to our guide on the different leather finishes.

HOW TO USE A STRIKING CLAW?

The punching claw will allow you to have a regular seam. Several factors must be taken into account to have a beautiful seam:

• Always keep the claw perpendicular to the leather and stable;
• Always go back 3 points;
• Always scratch with the net on your right;
• Always start by working the corners with a 2-tooth claw: the rule is that the point located in the corner must always point towards the center of the part;
• Never use a mallet with a 2-pronged claw as this may pierce the leather and damage it.

There is no direction to hold the claw: the point is the same on both sides.
We recommend using a plastic or polymer hammer to avoid damaging your tools.

The different types of striking claws:

You can discover 2 types of claws in our store:
1- The pricking point marking claws (straight line also called "comb") allow you to mark the leather with the right inclination to facilitate the "insertion" of the awl.
2- The diamond-tipped (diamond) punching claws allow you to pierce the leather like an awl with pliers. Be careful to keep it perpendicular otherwise your seam will be at an angle on the reverse side. If your leather is thick, we do not recommend piercing it completely but only on a large part of its thickness (pre-piercing): otherwise your stitch will not be pretty (risk of having a larger stitch on one side of the leather) .

For aesthetic reasons, we have a preference for the pricking tip.

What is the difference between a standard stitch and a reverse stitch?

The “reverse” claw stitch is symmetrical to the “standard” stitch. This stitch is generally used to sew in double claw or to make a connection on a creation that has been sewn with a professional sewing machine.

Claws with a "reverse" point are generally called "left-handed claws": this is an abuse of language, there are no left-handed or right-handed claws. As a reminder: there is no direction to hold the claw, the point is the same on both sides.

Which center distance (striking claw) should I choose?

The center distance is the distance between two points: it is to be chosen according to the item you wish to create: aesthetic choice. The "standard" for leather goods creations is the center distance 3.38 mm - n°8 (3 points per centimeter) . In order to know which center distance to choose for your creation, we invite you to consult our guide:

How to adjust the spacing/center distance of the last stitches?

When you only have a few points left to mark with your striking claw, there may be a slight offset. You must therefore adjust the spacing of the last points by eye or using our plexiglass template to avoid these offsets (points too large or too small).

WHAT ARE THE DIFFERENCES BETWEEN HAND SEWING OF LEATHER AND MACHINE SEWING?

Unlike machine sewing, the saddle stitch technique allows each of the two threads to pass over and under the layers of leather. The seam is therefore stronger: if one of the threads breaks, the seam does not come undone and can be repaired.

SEE THE GUIDE >

Sewing leather with a saddle stitch allows you to obtain a beautiful slanted stitch on both sides (right side and wrong side).

WHAT IS SIMPLIFIED LEATHER STITCHING?

The so-called simplified sewing consists of piercing the stitches using a round punch. This straight stitch is mainly intended for beginners.
