Rolled hem (serger)
A narrow, tightly wrapped edge finish produced on an overlocker by adjusting the stitch finger and tension so thread coverage rolls the raw fabric edge under.
intermediate · Overlockers & coverstitch
Rolled hem foot
A curled, funnel-shaped presser foot that folds a narrow raw fabric edge twice as it feeds, producing a tiny finished hem in a single pass.
intermediate · Presser feet
Rotary cutter
A round, razor-sharp blade mounted in a handle, rolled along a straightedge to cut fabric, especially multiple layers for quilting and garment pieces.
beginner · Cutting tools
Rotary cutter safety
Practices for handling a rotary cutter safely, including closing the blade guard between cuts, cutting away from the body, and keeping fingers clear of the blade path.
beginner · Workspace & safety
Rotary hook
A rotating mechanism beneath the needle plate that catches the upper thread's loop and carries it around the bobbin case to form a lockstitch.
intermediate · Machine anatomy
Ruffler foot
An attachment with an adjustable blade and gear mechanism that folds fabric into controlled pleats or gathers as it feeds beneath the needle.
advanced · Presser feet
Satin stitch
A tightly spaced zigzag stitch dense enough to form a smooth, solid line of thread, used for applique edges, monograms, and buttonholes.
intermediate · Stitches & settings
Seam gauge
A short sliding ruler with a movable marker used to measure and mark consistent small distances such as hem depths and seam allowances.
beginner · Marking & measuring
Seam puckering
Wrinkling or gathering along a stitch line caused by tension imbalance, a dull needle, or stitches that are too small for the fabric's weight.
intermediate · Maintenance & troubleshooting
Seam ripper
A small hand tool with a curved, sharp fork and a protective ball point used to cut and remove unwanted stitches.
beginner · Cutting tools
Seam roll
A firmly stuffed cylindrical cushion placed under a seam to press it open from the right side without leaving a ridge imprint on the fabric.
intermediate · Pressing tools
Servo motor (sewing machine)
An energy-efficient electric motor for industrial machines that starts instantly at the set speed and stops precisely, unlike a continuously spinning clutch motor.
advanced · Industrial machines
Sewing box
A container, often compartmentalized, used to store and organize sewing notions such as needles, thread, pins, and small tools.
beginner · Dress forms & workspace
Sewing machine electrical safety
Precautions for using a sewing machine safely, including inspecting the power cord, avoiding overloaded outlets, and unplugging the machine before changing needles or clearing jams.
beginner · Workspace & safety
Sewing room ergonomics
Arrangement of a sewing workspace, including chair height, machine and cutting table position, and lighting, to reduce strain during long periods of sewing.
beginner · Workspace & safety
Shuttle bobbin
A long, torpedo-shaped bobbin used in vibrating and transverse shuttle machines, distinct from the round bobbins used in modern rotary hooks.
advanced · Vintage machines
Singer 15 class
A widely produced vintage sewing machine platform known for its oscillating hook and full range of licensed and cloned versions manufactured worldwide.
intermediate · Vintage machines
Singer Featherweight
A lightweight, portable straight-stitch-only Singer model, most famously the 221, prized by collectors and quilters for its smooth stitch quality and durability.
intermediate · Vintage machines
Sleeve board
A narrow, two-tiered miniature ironing board sized to fit inside a sleeve or other tight tubular garment section for pressing without creasing the opposite side.
intermediate · Pressing tools
Spool pin
A small upright post on a sewing machine that holds the thread spool in place as thread feeds off toward the tension discs and needle.
beginner · Machine anatomy
Stabilizer (embroidery)
A backing material, in tear-away, cut-away, or wash-away form, placed under fabric to support it against the pull and density of embroidery stitching.
intermediate · Embroidery & software
Steam iron
An iron that releases pressurized steam through vents in its soleplate to help relax fibers and set creases and seams.
beginner · Pressing tools
Stitch length
The distance the feed dogs advance fabric between needle penetrations, typically measured in millimeters, adjustable for basting, regular sewing, or reinforcement stitching.
beginner · Stitches & settings
Straight stitch
The most basic machine stitch, formed by a single needle thread interlocking with a bobbin thread in a straight line, used for most seams and construction.
beginner · Stitches & settings
Tailor's chalk
A flat or triangular piece of chalk or clay-based marking material used to draw temporary lines and symbols directly on fabric.
beginner · Marking & measuring
Take-up lever
An oscillating arm on the machine head that pulls thread from the spool, feeds slack to the needle, and draws thread up after each stitch is formed.
intermediate · Machine anatomy
Tape measure
A flexible, usually fiberglass or cloth ribbon marked with inch and centimeter graduations, used to take body and fabric measurements around curves.
beginner · Marking & measuring
Task lighting for sewing
Focused lighting positioned at the sewing machine and cutting table to reduce eye strain and improve accuracy when threading needles or matching thread colours.
beginner · Workspace & safety
Teflon foot
A presser foot with a non-stick coated sole that glides smoothly over vinyl, leather, and other sticky materials without dragging or marking them.
intermediate · Presser feet
Tension disc
A pair of metal discs that the upper thread passes between, applying adjustable pressure to balance thread tightness against the bobbin thread for even stitches.
intermediate · Machine anatomy
Thread bunching
A tangled mass of thread, usually on the fabric underside, caused by incorrect threading, an unbalanced tension, or an improperly seated bobbin.
beginner · Maintenance & troubleshooting
Thread nest
A dense tangle of looped thread that jams beneath the fabric, usually caused by an unthreaded take-up lever or incorrect upper threading.
beginner · Maintenance & troubleshooting
Thread rack
A wall-mounted or freestanding storage rack with pegs or spindles that holds spools of thread visibly and within easy reach.
beginner · Dress forms & workspace
Thread snips
Small, spring-loaded scissors with short blades designed for quickly trimming thread tails and jump stitches without picking up full-size scissors.
beginner · Cutting tools
Thread tension
The balance of pull applied to the upper and lower threads so they interlock at the midpoint of the fabric layers, producing an even, flat stitch.
beginner · Stitches & settings
Topstitch needle
A machine needle with an extra-large eye and a deep groove designed to accommodate thick topstitching or decorative thread without excess friction.
intermediate · Needles
Tracing wheel
A tool with a small spiked or serrated wheel, rolled along pattern lines to transfer markings onto fabric, typically paired with dressmaker's carbon paper.
beginner · Marking & measuring
Transverse shuttle
An early sewing machine shuttle mechanism that travels side to side beneath the needle plate, common in machines predating the rotary hook.
