01Overview

Gutermann Mara 100 is a premium all-purpose sewing thread trusted by garment makers, quilters, and home sewers alike for its exceptional consistency and strength. Spun from 100% core-spun polyester, this thread combines a durable filament core with a soft spun finish, giving it the tensile strength to withstand high-speed industrial machines while remaining gentle enough for delicate fabrics. Its fine tex 80 weight makes it versatile for a wide range of projects, from garment construction and quilting to home decor and craft work, without adding unwanted bulk to seams.

What sets Mara 100 apart is its remarkably smooth, even finish, which allows it to glide effortlessly through the machine needle and tension discs, minimizing thread breaks, skipped stitches, and lint buildup. This reliability makes it a favorite among quilters who demand precision for piecing and machine quilting, as well as dressmakers who need clean, durable seams that hold up to repeated washing and wear. The thread's colorfast dyes resist fading even after multiple laundering cycles, ensuring that finished garments and quilts retain their vibrant hues project after project.

Available in an extensive palette of colors, Gutermann Mara 100 gives sewists the flexibility to match or contrast with virtually any fabric, making it a staple in sewing rooms and studios worldwide. Wound on generous spools, it reduces the need for frequent rethreading, saving time during long quilting or sewing sessions. Whether used for topstitching, bobbin work, or intricate quilting patterns, Mara 100 delivers professional-quality results, reinforcing why it remains a go-to thread for both hobbyists and professional needleworkers who prioritize durability, smooth performance, and lasting color.
