A leather needle has a wedge shaped cutting tip that slices a small slit rather than pushing fibres aside. Leather has no woven structure to part, so an ordinary point tears an irregular hole and the stitching perforates the material into a line that will split.
Where it belongs. Real leather and suede, in sizes 90/14 to 110/18 depending on thickness.
Where it does not. Faux leather, vinyl, coated fabric and leatherette all have a woven or knitted backing. A cutting point slices that backing and creates a tear line. Use a microtex or a universal on those, or a needle sold specifically for synthetic leather.
What else changes when sewing leather.
Every hole is permanent. There is no unpicking, so test seam placement on scrap and use clips rather than pins.
Lengthen the stitch to 3 to 3.5 mm. Short stitches perforate leather into a tear.
Do not backstitch. Reverse stitching punches a second set of holes in the same line. Leave long tails and knot them.
Use a walking foot or a roller foot, or put tape on the sole of an ordinary one, because leather sticks under a standard foot and will not feed.
And be realistic about the machine. A domestic machine handles garment leather and light hides. Upholstery leather and several layers of thick hide need a walking foot machine, and no needle changes that.
Questions people actually ask
Which way does the wedge face?
The orientation of the cutting edge varies by brand and it affects how the stitch line looks. Check the packet and test on scrap.
Can I sew leather with a universal needle?
On very thin garment leather, sometimes. The stitches look rougher, the holes are less clean, and it blunts the needle quickly.
