Modern sewing technology is a complex mechanism, the capabilities of which go far beyond the simple connection of two pieces of fabric. Many owners of household units do not even suspect that their device can perform operations typical of an industrial workshop. The key to expanding functionality is specialized sewing machine accessories, which transform standard stitching into a professional finish.
The use of additional devices allows not only to speed up the sewing process, but also to significantly improve the quality of the product. Precise fabric layout, ideal hem width and uniform edging become accessible even to beginners. In this article we will examine in detail the main types of accessories, the principles of their operation and the rules for safe operation.
Understanding the purpose of each piece of attachment opens up new horizons for the seamstress. You will be able to work with knitwear, leather, perform decorative seams and create complex designs without much effort. Let's look at how to select and use these tools correctly.
Classification and purpose of sewing feet
The main element that influences the advancement of the fabric and the formation of the stitch is the foot. This one sewing accessory presses the material against the needle plate. There are many modifications, each of which is tailored for a specific task. A universal foot is suitable for most operations, but for specific fabrics it may be ineffective or even dangerous for the material.
For example, when working with delicate fabrics such as silk or chiffon, a standard press may leave marks or puffs. In such cases, Teflon-coated feet or a roller mechanism are used. When working with knits and stretch materials, it is critical to use presser feet walking clamp, which advance the top and bottom layers of fabric simultaneously, preventing deformation.
⚠️ Attention: Never use a metal foot to work with leather or leatherette without a Teflon coating - the material may stick to the metal, leading to thread breakage or needle breakage.
Selecting the correct clamping device depends on the type of operation. For sewing in zippers, there are models with an offset center, allowing the needle to get as close as possible to the teeth. To sew on buttons, a foot without a bottom is used, which secures the button and allows the needle to oscillate from side to side.
Devices for finishing edges and hems
One of the most labor-intensive operations in sewing is processing cuts. Manual marking and pinning takes a lot of time and does not always guarantee a perfect result. Special hems solve this problem automatically. They guide the fabric, turning the edge to the required width while sewing.
The most popular hem feet are those with a spiral groove. The fabric is tucked into this groove and twisted into a tube, creating a narrow scar. This is an indispensable device for processing the edges of scarves, napkins and light blouses. The width of the rib depends on the size of the spiral channel, so there are several of these legs for different tasks.
- 🧵 Foot for secret hemming - allows you to bend the edge of the fabric so that the thread of the line will be almost invisible from the front side.
- 📏Edging Foot - has a guide for inserting braid or bias tape, ensuring a perfect fit along the edge of the product.
- ✂️ Foot for hemming jeans - has a special protrusion that allows you to make a thickened seam at the joints of denim clothing.
Using such devices requires some skill. The fabric should be fed evenly, stretching it slightly before entering the foot. If the fabric is too slippery, you can lightly iron it first or use starch spray to stiffen it.
To perfectly hem thin fabrics, pre-glue the cut with a narrow strip of non-woven fabric - this will add rigidity and prevent the edges from fraying during operation.
Specialized feet for decorative work
Decorative sewing requires high precision and is often performed at high speeds. Decorative feet They have an open front for excellent visibility of the needle. This allows the seamstress to precisely control the seam line and the direction of movement of the fabric, which is especially important when making complex patterns.
Use the darning and embroidery foot to create stunning raised stitches. It has a spring mechanism that rises and falls with the needle. This allows the fabric to move freely under the needle in any direction, creating patterns similar to machine embroidery. This technique is called free-motion machine embroidery.
Another popular device is the foot for sewing on sequins and beads. It has a special groove through which the thread with stringed decorations is fed. The device automatically places the sequin and secures it with a stitch. This significantly speeds up the process of decorating evening dresses and suits.
| Presser foot type | Purpose | Design Features |
|---|---|---|
| Open foot | Decorative stitches, applique | Open spout for viewing |
| Embroidery foot | Free embroidery, darning | Spring mechanism, no bottom |
| Sequin foot | Sewing on sequins and beads | Thread feed groove with decor |
| Triple presser foot | Decorative stitching in 3 threads | Three needle holders, wide clamp |
Mechanisms for advancing and working with difficult tissues
Working with multi-layered structures, such as quilts or coat fabrics, often presents the problem of layer slippage. The top layer of fabric may move faster than the bottom layer, causing the product to warp. To solve this problem, use upper conveyor (walking foot).
This device is attached to a needle holder or a special rod and synchronously with the lower conveyor advances the fabric. The teeth of the upper conveyor press and move the top layer, while the lower teeth work with the wrong side. This ensures the patterns match perfectly and there is no shrinkage.
⚠️ Attention: When installing the walking foot, be sure to lower the presser lever of the regular foot or remove it to avoid damaging the machine mechanism. Make sure the mounting screw is securely tightened.
Roller feet are used to work with leather, vinyl and other materials with a high coefficient of friction. Instead of a flat sole, they have rotating rollers that glide easily over the surface of the material. This prevents sticking and ensures an even sewing speed.
The secret of working with leather
When sewing leather, use a silicone foot or place a strip of masking tape on the sole of a regular metal foot - this will reduce friction and improve progress.
Devices for sewing in zippers and fasteners
Sewing in a zipper is one of the operations that most often causes difficulties for beginners. The standard foot does not allow you to get the needle close enough to the spiral teeth. Special zipper claws have an offset guide that allows the needle to fall close to the lock.
There are universal zipper feet that can be moved from right to left, and specialized ones - left and right. For hidden zippers, narrow tabs with deep grooves are used, which “hug” the spiral and hide it in the seam. This makes the fastener almost invisible on the finished product.
When working with an invisible zipper, it is important to properly prepare the fabric. The cut must be finished with an overlocker or zigzag before sewing in the zipper. The presser foot guides the fabric so that the needle passes right into the fold of the fabric, hiding the zipper tape.

Installation and safety rules for operation
Any sewing machine attachment requires correct installation. Improper installation may result in needle breakage, machine damage, or operator injury. Before attaching any foot, you must raise the needle to the highest position and lower the presser foot lever.
Fastening is carried out either with a screw or with a latch (snap-on system). With screw feet, it is important not to overtighten the screw, but also not to leave it loose. The foot should fit tightly, without play. When using the quick change system, you need to wait for the characteristic click that locks the device.
Operational safety also depends on the choice of needle. The appropriate needle must be used for each type of fabric and foot. A blunt or bent needle combined with a specialized clamp can cause a serious accident.
A basic safety principle: Always unplug the machine or lower the gas pedal when replacing presser feet and needles to avoid accidentally pricking your finger.
Regular cleaning and lubrication of the feet will prolong their service life. Lint and thread residues may accumulate on the teeth of the conveyor and the sole of the foot, which impairs the advancement of the fabric. Clean accessories with a soft brush after each project.
Frequently asked questions (FAQ)
Can feet from one brand of sewing machine be used on machines of another brand?
It depends on the type of fastening. There is a low pressure standard (Low Shank), which is universal for most household machines (Brother, Janome, Singer). However, machines with high shank or industrial models require specific presser feet. Always check compatibility before purchasing.
How often should the presser feet be changed?
Paws do not have a strict expiration date. Metal ones last for decades. Plastic or Teflon-coated feet require replacement when the coating wears off and begins to scratch or seize the fabric. Visually inspect the sole before important projects.
Why does the foot scratch the fabric?
This most often occurs due to roughness on the sole of the metal foot or the use of an uncoated foot for slippery fabrics. The solution is to polish the sole with fine sandpaper or use a paper backing (tracing paper) under the seam.
Do I need to lower the feed dogs when using the embroidery foot?
Yes, with free-motion embroidery (darning), the teeth of the lower feed are usually lowered so that you can move the fabric yourself. However, some modern machines allow you to leave the teeth raised if you use a high-gap presser foot. Follow the instructions for your model.
