This is the most common mechanical stitch made by a sewing machine and creates a refined, smooth seam that doesn’t pucker. It uses one needle and two threads, an upper and lower thread, which lock together in the fabric and prevent either thread from pulling out of the material.
Similar to the single needle lockstitch, this technique uses two needles, is less labor intensive, but also more prone to puckering. If you look inside the leg seam of any standard pair of Levi’s, you’ll see this stitch at work.
This is a machine that uses more than one needle in the sewing head and can sew the same design onto separate garments at the same time, while producing an array of fabric stitching effects. A multi-needle machine usually has between four to 16 needles, though it can have upwards of 20, allowing it to hold and utilize different thread colors concurrently. It is most commonly used to make embroidery patterns, with the more advanced machines able to trim and change colors automatically.
This is a method for feeding a workpiece through a sewing machine as it’s stitched. It is most useful on heavy materials and is more commonly found on industrial heavy duty machines than household ones. It’s called a walking-foot because the piece on the machine is reminiscent of an upturned elf shoe.
This is a finishing stitch that sews over the edge of a material to make an edging, decorative hemming or seaming. This stitch requires a special machine that can create loops on the edges of a material. “Serger” is often used interchangeably with “Overlock” though the term technically is for an overlocking machine that uses automated cutters.
AKA. Programmable Pattern Lockstitch - Automated machines that sew patterns up to 2,700 stitches per a minute. The machine moves on the x and y axis, allowing it to accurately recreate programmed designs and save the data for future use.
This is a series of extremely close stitches that are used to reinforce garment areas subject to stress or additional wear. Such areas usually include pocket openings, button holes, belt loops, fly openings, tucks, pleats and the corner of collars.
This is a type of flatlock-stitch that can be executed by a specialized machine, forming the thread into a flat, interlocking pattern, which is incredibly durable and comfortable against the skin. This type of stitch can be found on wetsuits, locking two pieces of neoprene together.
A two piece metal or plastic eyelet used to protect a hole in a material. The grommet serves as a way to help drain, cinch or attach points on the material and are created with a manual kick press or automatic grommet machine.
This machine is used to quickly and accurately cut rolls of elastic, webbing, ribbons, belt loops, hook and loop, nylon cords, leather, safety belts, rubber and vinyl. Hot strip cutting seals edges of synthetic materials with heat to prevent fraying.
This is welding technique that uses ultrasonic acoustic vibrations to bond two materials together. It is commonly used to join plastics or dissimilar materials without the need of bolts, nails, soldering or adhesives.
