Bartacks

Construction — one of 70 in the glossary


A dense cluster of tight zigzag stitches worked across a short span to lock a seam at a point that takes strain — pocket corners, belt loops, the base of a placket, the ends of a fly. They concentrate reinforcement exactly where a garment tears first, at almost no cost. Their presence on a spec sheet is one of the better indicators that a garment was built for work rather than for display. They also create a thick, raised patch that will not flatten under a heat press platen, so keep transfers clear of them.

Concentrating strength at one point

A bartack is a dense cluster of tight zigzag stitches worked back and forth across a short span. It does not join anything new — it reinforces a point that is already stitched.

The places it goes are the places load concentrates: pocket corners, belt loops, the base of a placket, the top of a vent, the ends of a fly.

Without it, that load lands on the last stitch of an ordinary seam, and a seam always fails at its end.

Where to look

Pocket openings, at both corners. Vent tops. Placket bases. Belt loops at both ends.

They are visible as a short, solid block of stitching, usually the same colour as the seam.

Their absence on a garment that will take real use is a fair prediction of where it will fail first, and it is one of the quickest things to check on a sample.

Common questions

What is a bartack?
A dense cluster of tight zigzag stitches across a short span, reinforcing a point that takes strain — pocket corners, belt loops, the base of a placket, the top of a vent.
Why do pockets have bartacks?
Because the corners of a pocket opening take all the load when a hand goes in, and a seam fails at its end. The bartack spreads that load instead.
How do I know if a garment has bartacks?
Look for a short solid block of stitching at pocket corners, vent tops and belt loop ends. Their absence predicts where the garment will tear first.
