What Thread to Use for Different Fabrics
Using the wrong thread can ruin an otherwise perfect project. Learn the simple rules for matching thread to fabric.
The Basic Rule
**Match your thread fiber to your fabric fiber.**
- Cotton fabric → Cotton or poly-cotton thread
- Polyester fabric → Polyester thread
- Silk fabric → Silk or polyester thread
- Wool fabric → Wool or polyester thread
Thread Weight Explained
Thread weight indicates thickness (counterintuitively, higher numbers = thinner thread):
| Weight | Best For |
|---|---|
| 30wt | Topstitching, decorative |
| 40wt | General sewing, quilting |
| 50wt | Piecing, lightweight fabrics |
| 60wt | Fine fabrics, machine embroidery |
