I am a rough user of any products. Cause that’s how I am! 😑 And that’s why my bag strap keeps slipping away & breaking down. I am annoyed as hell to keep fixing it! I need a back up. I can’t just fix things up or buy new things.
So I ask my stitcher friend about it. She very casually said Do box stitch sewing machine. She even added that it’s easy to do it, too. Basically,
Machine Box Stitch
To do a box stitch on a sewing machine, sew a square or rectangle shape by stitching straight lines along all four sides.
I was like, why didn’t I know it before? I was struggling all alone? I sat down with my machine cause I had to try it.

What Is A Box Stitch Sewing Machine?
A box stitch sewing machine is basically a box-shaped stitch. It is a heavy-duty industrial setup that automatically sews reinforced patterns.
It is similar to the classic BOX-X pattern items, like straps, harnesses, and seatbelts. It’s called a “shape tacker” or “bar tacker,” and it’s built to handle thick materials and high-stress points.
How To Do Box Stitch Sewing Machine?
I take out my broken strap and sit down to do a box stitch,
- Position the Needle
- Do Stitch Straight
- Diagonal Stitch to Opposite corner
- Turn The Fabric And horizontally stitch
- Stitch the Second Diagonal of the “X”
- Sew the Bottom Edge
- Complete the Last vertical stitch
- Lock the Stitch
Position the Needle and Start Inside the Edge
I’ve got my fabric lined up and ready to go. I’m placing the presser foot down and positioning my needle just a little in from the edge.
I’m definitely not right at the edge, because if that thread ever breaks, my whole stitch could unravel. I lower the needle and take about 2–3 short straight stitches forward to secure the start. That’s the perfect length for a variety of materials.
This is going to be one side of the box.
Now I Stitch Straight Down Along The Side
Now I stitch straight down along the side of the box shape. It’s like drawing the left wall of the box with thread. I make sure my line is even and clean.
I’m not too long, not too short. And stop just before I reach the bottom corner, kinda like an overlock stitch.
Diagonal Stitch to Opposite Corner
Here comes the first diagonal! I rotate the fabric so the needle lines up diagonally across the box. I sew a clean line from the bottom left corner up to the top right. It forms the first diagonal line of the “X.” Feels satisfying, right?
Turn The Fabric And Stitch The Horizontal Line
Now I turn the fabric again so I can sew the top of the box. I stitch a nice, straight line across to the top left corner. This gives the top edge that clean, boxed look.
Stitch the Second Diagonal of the “X”
Time to complete the “X”! I rotate the fabric once more and sew diagonally from the top left corner down to the bottom right. And just like that—boom—the cross part of the Box X tacks is done.
Sew the Bottom Edge
Now I need to close off the bottom of the box. I can either turn the fabric around to sew forward, or just hit reverse and backstitch carefully across the bottom edge. I prefer to rotate so I can see where I’m going, but it’s entirely up to you.
If you prefer an easier option, you can also use a cover stitch.
Complete the Last Vertical Line
Time to finish the last side! I stitch straight up the right edge of the box to complete the shape. Everything’s looking symmetrical, and those corners are tight. Almost done!
Lock the Stitch
To wrap it up, I sew a few back-and-forth stitches to lock the thread in place. This keeps the box X sturdy and secure. Snip off the threads, and boom You’ve just stitched a solid box X.

Frequently Asked Questions
Can I sew a box X with a regular sewing machine?
Yes! No fancy machine required—you just need a straight stitch and the ability to pivot your fabric cleanly.
Do I need to backstitch for a box X?
Definitely. Backstitching at the beginning and end helps secure the stitch, preventing it from unravelling.
Should I draw the box and X with a fabric pen first?
You can! I sometimes sketch a light outline with a disappearing fabric pen when I want extra precision, especially on dark or slippery fabric.
Conclusion
And that’s how I manually sew a box stitch sewing machine. It’s one of those stitches that looks simple but packs a punch in strength.
Now that I’ve got the hang of it, I use it every time I want to ensure a strap or loop stays in place for the long haul.
Trust me, once you try it, you’ll wonder how you ever skipped it before. 💪
