Quick answer

Gütermann Sew-All thread is a 100% polyester all-purpose thread that works for both machine and hand sewing on a wide range of fabrics. It is a solid default for beginners and everyday projects, especially when you want one thread that handles cotton, blends, and synthetics without changing spools. If you sew heirloom cotton quilts and prefer cotton thread, you may want a cotton option instead.

What makes Gütermann Sew-All a reliable default

Gütermann Sew-All is a No. 100 weight thread, which is a medium weight that balances strength and visibility in seams. It is made of 100% polyester, so it has some stretch and resists breaking under stress. The recommended needle size is NM 70-90 / US 10-14, which covers most light to medium weight fabrics. This thread works for both machine and hand sewing, so you can use the same spool for basting, hemming, and construction. For beginners, that simplicity reduces decision fatigue and the risk of using the wrong thread.

How to match thread fiber to your fabric

The general rule is to match thread fiber to fabric fiber when possible. For cotton fabric, cotton thread blends in best and presses flat, but polyester thread like Sew-All is stronger and more colorfast. If you are sewing cotton that will get heavy use, such as a pillowcase or tote bag, polyester thread is a practical choice because it holds up to washing. For synthetic fabrics like polyester or nylon, polyester thread is the right match because both have similar stretch. For stretchy knits, you need a thread with some give, and polyester works well. Wool or silk fabrics often pair best with cotton or silk thread, but Sew-All can work if you adjust tension and needle size.

When to choose polyester vs cotton thread

Choose polyester thread like Gütermann Sew-All when you want durability, colorfastness, and a thread that works across many fabric types. It is a good choice for bags, home decor, kids' clothes, and any project that sees frequent washing. Choose cotton thread when you are sewing heirloom quilts, want a matte finish that blends with cotton fabric, or plan to iron seams flat without the thread melting. Cotton thread has less stretch, so it is not ideal for knits or stretchy fabrics. If you are unsure, polyester is the safer all-purpose option for most beginners.

Needle and tension tips for smooth sewing

Use a needle size in the recommended NM 70-90 / US 10-14 range. For lightweight cotton, start with a 70/10 or 80/12 needle; for medium weight fabrics like canvas or denim, use a 90/14. If you see skipped stitches or thread shredding, change to a fresh needle and rethread the machine. Polyester thread can stretch slightly, so keep tension moderate; too much tension can cause puckering. Always test on a scrap of your project fabric before sewing the final seams.

Caring for projects sewn with polyester thread

Polyester thread is durable and colorfast, but high heat can damage it. When washing, use warm or cool water and avoid bleach. In the dryer, use low heat or air dry to prevent shrinkage and thread degradation. If you iron, use a moderate setting and press on the wrong side or use a pressing cloth. For projects that need frequent washing, like the pillowcase from a beginner kit, polyester thread helps seams stay strong. Cotton thread may fade over time with repeated washing, while polyester holds color better.

Decision rules for choosing thread

  • If you sew mostly cotton and want one thread for everything: Use Gütermann Sew-All polyester thread. It works on cotton, blends, and synthetics, and it is strong enough for bags and home decor. Best all-purpose choice for beginners.
  • If you sew heirloom cotton quilts and want a traditional look: Choose a cotton thread instead. Cotton thread blends better with cotton fabric and presses flat, but it has less stretch and may fade with heavy washing. Polyester is not the best match for heirloom quilting.
  • If you sew stretchy knits: Use polyester thread like Sew-All because it has some give. Cotton thread can break when the fabric stretches. Match stretch with stretch.
  • If you are not sure which needle to use: Start with a universal needle in size 80/12 for medium weight fabrics. For lightweight cotton, try 70/10; for heavier fabrics, try 90/14. When in doubt, test on a scrap first.
