A fine professional all-rounder
Made for clean construction seams and polished everyday sewing
Mara 100 balances a refined thread profile with the dependable performance required for regular sewing. It is especially useful when a heavier topstitch thread would overpower the fabric or make seam allowances feel bulky.
Garment construction
Sew shirts, dresses, trousers, outerwear, uniforms, activewear and many other woven or knitted garments with neat seam definition.
Overlock and coverstitch
Suitable for overlock, safety and coverstitch seams when the machine, needle and tension are set for the material.
Buttonholes and detail
Create straight or eyelet buttonholes and refined decorative stitching without the heavy appearance of bold topstitch thread.
Workroom versatility
A practical 1000m format for alterations, samples, repeat garments, home textiles and professional sewing rooms.
Micro Core Technology
Engineered for a smooth, uniform stitch
Mara uses Gütermann's Micro Core Technology, a microfilament polyester core-spun construction. The fine, even cross-section supports balanced stitch formation, reliable unwinding and a clean surface with very little loose fibre around the machine.
Fine and even
A consistent thread structure helps seams look smooth and regular from the first stitch to the last.
Subtle lustre
The smooth surface gives colours a polished, silk-like appearance without a coarse or fuzzy finish.
Reliable running
Designed for dependable performance in suitable domestic and industrial sewing setups.

Machine and needle guidance
Start with NM 70 to 90 and test the complete seam
Gütermann recommends needle sizes NM 70 to 90, equivalent to US 10 to 14, for Mara 100. Choose the needle point for the material, then test through the same layers and stabilisers used in the finished project.
Choose the pointUse the correct needle system and point for woven, knit, denim, leather or coated materials.
Balance the tensionAdjust gradually until the stitch locks cleanly between the layers without puckering or loops.
Test the seamCheck the stitch length, seam appearance and strength on a project offcut before sewing the finished item.
Thread the machine with the presser foot raised so the thread enters the tension discs correctly.
Match the needle point and size to the fabric rather than choosing by thread alone.
Use the same fabric layers, interfacing and stabiliser in the test seam.
Keep the shade code with project notes for accurate reordering.
For structural, safety-critical or outdoor seams, confirm the exact thread specification required by the end use.

Common questions
Gütermann Mara 100 FAQs
What is Mara 100 best used for?
It is a fine professional general-purpose thread for garment construction, neat decorative seams, buttonholes, overlock and coverstitch applications, plus many workroom and home textile projects.
What fibre is Mara 100 made from?
Mara 100 is made from 100% polyester using Gütermann Micro Core Technology construction.
Can I use it in a domestic sewing machine?
It suits many domestic machines when the correct needle, threading and tension are used. The 1000m spool must also sit securely on the spool pin or a suitable thread stand.
Is Mara 100 a heavy topstitch thread?
No. Mara 100 is Tex 30 and gives a relatively fine stitch line. Choose Mara 70 or Mara 50 when you want increasingly stronger visual definition and the machine can accommodate the heavier thread.
Which needle size should I use?
The official guidance is NM 70 to 90, or US 10 to 14. Choose the needle point and exact size for the fabric, then test the complete seam setup.
How do I choose the colour?
Select the exact numeric shade code in the product options. The colour squares help with browsing, while the code is the precise reference for selection and reordering.
How much thread is supplied?
Each purchase supplies one 1000m spool in the selected shade code.
Is this the same as Gütermann Sew-All?
No. Mara 100 is an industrial and professional MCT thread specification. Although both are versatile polyester sewing threads, select by the named product, Tex size, spool length and shade code rather than treating them as identical.
