Buying Guide: Bonded Polyester Thread For #92 Projects
What to consider when buying bonded polyester thread:
- Strength and UV resistance: Look for UV-stable fibers and bonded threads for outdoor use to prevent weakening and fraying.
- Weight and thickness: Tex and weight (such as Tex 69 or Tex 70) influence how well the thread handles heavy fabrics. Heavier fabrics benefit from finer Tex numbers paired with bonding.
- Lint and seam integrity: Bonded threads reduce lint and provide cleaner seams, especially on high-speed sewing or upholstery work.
- Color variety and yardage: For large projects, choose high-yardage spools or packs to minimize color mismatches and running out mid-project.
- Application fit: Marine, outdoor furniture, and automotive uses require more abrasion and UV resistance than general crafting.
- Compatibility: Confirm the thread’s compatibility with your needle type, machine brand, and fabric type.
