S
ewing Thread Guidelines
|
|
|
|
|
||||
Sewing Thread Color & Texture
|
|
Match thread to the fabric color for a seamless look or contrast for decoration. Use thin thread for light fabrics and thick for
heavy materials. |
|
|
||||
Performance Matching
|
|
The sewing thread should mirror the fabric's raw material for consistent performance. Use fiber-specific threads for strength and
shrink resistance, and special threads for heat resistance, flame retardance, or waterproofing where necessary. |
|
|
||||
Selection by Seam Type
|
|
Choose thread with appropriate fastness and elasticity for the seam type, like chain stitch. Use multiple thread types across
different garment parts for optimal results, ensuring security for seams and wear resistance for locks. |
|
|
||||
Needle and Thread Sizing
|
|
Select thread thickness based on needle size—fine threads for small needles and vice versa.
|
|
|
||||
Quality Considerations
|
|
Account for the garment's quality, and requirements for washing, ironing, finishing, and storage.
