Why Thread Choice Matters

Leather is heavy and tough, so regular thread can snap or fray easily. Using a proper leather thread:

  • Strengthens seams for long-lasting wear

  • Prevents skipped stitches or puckering

  • Enhances the overall look of your jacket

Types of Thread for Leather Jackets

1. Polyester Thread

  • Strong, flexible, and widely available

  • Ideal for machine sewing leather

  • Resistant to abrasion and UV damage

2. Nylon Thread

  • Extremely durable and slightly elastic

  • Perfect for heavy leather or multi-layered projects

  • Great for topstitching and visible seams

3. Waxed Thread (for Hand-Sewing)

  • Smooth, coated finish allows easy hand stitching

  • Reduces friction and prevents fraying

  • Gives a rustic, artisanal look to hand-sewn seams

Tips for Choosing the Right Thread

  • Match Thickness to Leather: Heavy leather needs thicker thread (e.g., Tex 70 or higher).

  • Color Matters: Choose a contrasting thread for style or match for a seamless look.

  • Test First: Always sew a small scrap to ensure thread strength and appearance.

  • Use Quality Thread: Cheap thread can break or fray during sewing, ruining your work.

FAQs

Q1: Can I use regular cotton thread for leather jackets?
A: No, cotton thread is not strong enough for leather and can break easily. Use polyester, nylon, or waxed thread instead.

Q2: What thread thickness is best for thick leather?
A: Heavy leather requires thicker thread, such as Tex 70–90 or size 69, to handle the stress of seams.

Q3: Should I hand-sew or machine-sew with leather thread?
A: Both are possible. Use waxed thread for hand sewing and polyester or nylon for machine sewing.

Q4: Does thread color affect durability?
A: Color doesn’t affect strength, but high-quality colored thread is treated to resist UV and abrasion.

Q5: Can I topstitch with waxed thread?
A: Yes, waxed thread gives a bold, artisanal look perfect for decorative topstitching on jackets
