Quick answer

Use a tapered awl to open a clean hole through leather before each stitch, guiding the needle through without forcing or damaging the thread.

Why a tapered awl works better than a straight awl for leather

A tapered awl has a blade that narrows to a sharp point and widens gradually. This shape lets you start a small hole and enlarge it only as deep as needed, reducing stress on the leather fibers. Straight awls can tear or distort the hole, especially in thick or dense leather.

When to use an awl vs. a chisel or punch

Use an awl when you need a hole exactly where the stitch goes, not pre-marked by a chisel. It is also the tool of choice for curved or tight corners where a chisel cannot reach. For long straight seams, a chisel or punch is faster and more consistent.

Step-by-step: Using the tapered awl for hand stitching

Mark your stitch line: Use a stitch marker, wing divider, or a ruler and awl to lightly score a guide line. Work on a cutting mat or piece of scrap leather to protect your surface. Skipping the guide line often leads to uneven spacing and crooked seams.
Pierce the first hole at a 90° angle: Hold the awl perpendicular to the leather surface. Push the tip straight in until it emerges on the other side. Rock the awl gently side to side to enlarge the hole to the diameter of your needle and thread. Piercing at an angle creates a slanted hole that can cause the needle to exit off your stitch line.
Insert the needle and pull the thread through: With the hole open, push the needle through from the same side you pierced. Pull the thread until the stitch is snug but not tight enough to pucker the leather. Forcing the needle through a hole that is too small will fray the thread and stress the leather.
Repeat for each stitch, one hole at a time: After completing a stitch, move to the next mark, pierce a new hole, and pass the needle through. Work in a consistent rhythm to keep tension even. Piercing multiple holes ahead of time can cause the leather to shift and misalign your stitch line.
Finish with a backstitch or knot: After the last stitch, pass the needle back through the previous hole and pull tight. Tie a square knot close to the leather surface and trim the thread tails to ¼ inch. A loose knot or long tail can unravel over time; burn the cut end slightly with a lighter to seal it.
