Detailed explanation of the key points of the process at the joint of clothing

When customers complain about clothes being “twisted,” “thick at the joints,” or “patterns not aligned,” the real problem usually lies in the stitching. In my years working with buyers, the joint area of garments is always the most critical.

Stitching methods, hemming treatment¹s, and alignment control² at garment joints determine the final visual, comfort, and durability of a product.

I’ve seen beautiful fabric ruined by bad alignment. But when the joint process is right, the whole piece elevates instantly.

What are the stitching methods? How to choose different designs and fabrics

Stitching isn't just functional—it shapes the structure and look of a garment. Choosing the wrong one can ruin fabric or kill stretch.

Common stitching methods³ include flat seams, double-needle seams, jujube seams, and more—each for a different fabric and tension level.

Structural differences and usage scenarios of flat seams, hemming, double needle seams, and jujube seams

Different seam types affect stretch, strength, and comfort.

What is the difference between knitted splicing and woven splicing in terms of stitching methods?

Knitted fabrics stretch—so stitches must move with the fabric.

• Knitted Splicing: Flat seam, overlock, cover stitch
• Woven Splicing: Lockstitch, jujube seam, topstitch

Using woven techniques on knits leads to breakage. Using knit stitches on wovens weakens structure.

Hemming treatment is not only for beauty, but also the key to improving the durability of clothing

Hemming seals edges. A good hem prevents fraying, adds structure, and makes clothes look finished.

From simple lock hemming to fine rolled edges, the hem choice must fit the fabric thickness, drape, and product level.

Common hemming methods: process structure and comparison of lock hemming, curling, pressing, and rolling

Each hem has a different edge finish and tension—important in keeping joints smooth.

How to make the hemming at the splicing line not thick and not run?

Tips:

• Trim seam allowance before folding
• Use different thread tensions at intersection
• Switch needle sizes to adapt to fabric stack
• Flatten with heat or steam during finishing

Always reduce bulk and prevent seam buildup at joints.

Alignment control determines the quality of splicing, and accurate alignment of flowers, stripes, and structures is the core ability

Perfect alignment isn't easy, but it defines premium craftsmanship. Especially for patterns, plaids, and stripes.

If one side is off by even 2mm, the visual error becomes obvious on the finished piece.

How to keep the pattern/check/line accurately aligned during splicing?

• Use transparent templates or grid lines
• Match notches on both panels
• Pin or clip along stripes before stitching
• Sew slowly with constant realignment

Pre-planning and marking are essential.

In which links are misaligned common mistakes? How to prevent it in advance?

Always confirm alignment before final stitching.

Process challenges and coping skills of special splicing structures

Special splicing = More risks. Different materials, curved shapes, or 3D panels require technical planning.

Without adapting stitch type and support method, seams may warp or wrinkle.

What technical details should be paid attention to in three-dimensional splicing, splicing of different materials, and open splicing?

• 3D Splicing: Clip notches in curved areas to release tension
• Mixed Materials: Use compatible needles and threads for each material
• Open Seam Splicing: Use reinforcing tape or fusing

Always test with a small sample before scaling.

What should I do if the stitching line is prone to wrinkling and warping? Is it necessary to add pressure strips or linings?

Yes. Wrinkles happen due to:

• Fabric pulling
• Uneven tension
• Incompatible thread/fabric combo

Add pressure strips (bias tape, fusing) to stabilize. For sheer fabric, use organza strip.

How to achieve stable consistency in stitching between pattern making and bulk goods?

The gap between samples and bulk often comes from unclear technical markings.

Controlling consistency means marking well, training production teams, and using dies or guides.

How to mark the stitching position on the pattern? Is it necessary to make a craft die?

• Add notches on seams
• Use double-notch for front/back distinction
• Include grain lines and balance points

Yes, making a sewing die or mold improves speed and accuracy in production.

From sample clothing to bulk goods, how to control the alignment error within the qualified range?

Consistency is a team effort between pattern, sewing, and QC departments.

Conclusion

Garment joints are where craftsmanship shows. Choose the right stitch, finish the hem cleanly, align perfectly—and the whole piece speaks of quality.
