Zero Waste Pattern Cutting: Process, Benefits, and Limits

As we all know, the fashion industry produces tons of waste via various production processes. Sustainability enthusiasts devised several methods to deal with this waste. One of these methods is zero-waste pattern cutting (ZWPC), which tackles fabric waste at the garment's inception stage.

The pattern pieces fit together like a jigsaw, reducing the scraps often left behind after cutting. We can trace the origins of ZWPC to Japanese kimonos and Indian sarees, which were constructed from a single fabric with little to no cutting. 

Keep reading as we examine the basic definitions and processes of pattern cutting. We will also discuss the concept of zero-waste sewing patterns, how they are created, and their benefits and limitations.

What is pattern cutting?

Pattern cutting is an essential aspect of cloth making in the fashion industry. It is one of the first steps in turning a fabric piece into wearable apparel like a dress, trousers, skirt, and more. It involves creating a template matching the measurements of a body type and using it as a blueprint for cutting out the fabric before joining the pieces by the seams. 

Creating sewing patterns requires expertise, creativity, and an understanding of garment construction techniques. Fashion designers draft sewing patterns on paper with pencil or chalk, using body measurements and calculations for sleeves, pockets, and other garment parts. 

All garments begin with basic blocks like sleeves, skirts, trousers, and bodice length. Pattern drafting creates these blocks on paper. Doing this on paper gives designers more room to make adjustments, change style lines, and manipulate darts to bring the cloth to life. 

Several clothing brands use pattern-cutting methods to help them maintain their unique styles through various fashion seasons and trends in multiple fabrics and prints. Some pattern-cutting techniques are draping, subtraction pattern cutting, computerized pattern cutting, flat pattern cutting, zero-waste pattern cutting, Japanese pattern cutting, and the transformational reconstruction technique. 

What is zero-waste pattern cutting?

ZWPC is a method of cutting fabrics without wasting any material. It is one of the many solutions geared towards reducing waste in the fashion industry. The zero-waste method includes sustainability at the initial stage of garment design. 

Zero-waste sewing patterns are better than conventional sewing patterns because they account for the waste generated during the design and cutting process of clothing construction. Research shows that 15% of fabric is lost during the cutting process when conventional sewing patterns are used¹. 

About 10-20% of fabric is sent to landfills when making adult clothes, and 10% of waste occurs during the construction of trousers. Other clothing items like jackets, blouses, and underwear generate more waste during the pattern design and cutting stage.

Zero-waste Design Practices Before

We can trace zero-waste design back to ancient civilizations by observing ethnic costumes and traditional national dresses. Greek, Indian, and Japanese fashions practice efficient fabric utilization, which prevents unnecessary waste. 

Ancient Greek and contemporary Indian fashion share a common technique of using an uncut, rectangular piece of fabric skillfully draped on the body. These old designers do not cut or sew any fabric part before wearing it. These ethnicities drape and pin in various ways, exploring the multiple possibilities of styles.

The Japanese kimono is also a zero-waste design. Japanese designers arrange the pattern pieces directly on the fabric to utilize its length and width. This meticulous process, similar to a jigsaw puzzle, ensures no fabric is wasted during cutting. 

Even if there's excess fabric left, Japanese designers use the scraps to enhance the neckline through pleating. The curvature of the sleeve's lower end accommodates excess seam allowance on the inner side. If zero-waste sewing patterns were prominent in ancient times, why are we just learning about them now? 

Zero-waste design at the initial stage of garment construction became less prominent because of the rise of industrialization and fast fashion. In the old days, humans placed more value on textiles than we do in the modern age because of how labor-intensive it was. They didn't want to waste any part of the fabric.

However, technological advancements were made in the fashion industry as the Industrial Revolution took the world by storm. Textile production became easy and efficient, making it cheap and easy to access. Hopefully, zero-waste sewing patterns will take the fashion world by storm in the coming years.

The Process of Cutting Zero-Waste Pattern Pieces

The design and cutting of zero-waste patterns depend on the cloth type and fabric width. Zero-waste designers have to work within the confines of the fabric width. You can not make a zero-waste dress, shirt, or pants without understanding the fabric's width because it is the foundation of the design.

Before attempting zero-waste garments, designers must understand the fundamentals of shapes and form manipulation and how they interact with the consumer's body. Zero-waste garments are above elementary shapes, meaning understanding the connection between patterns, fabric, and body contours is crucial. 

According to Japanese Designer Tomoko Nakamichi, you can make clothes from any geometric figure because they drape elegantly, producing beautiful shapes. Tomoko Nakamichi makes zero-waste sewing pattern pieces with circles, triangles, and squares because the excess fabrics flare and drape elegantly³.

Two standard methods are used to draw zero-waste garment patterns. One involves interlocking clothing elements like collars, cuffs, gussets, pockets, and trims like a jigsaw puzzle. Another consists of draping geometric patterns on form models to form clothes. 

Zero-waste pattern design isn't restricted to these two techniques or fixed guidelines. It only adheres to a fixed rule, reducing wasteful scraps on the table or floor after cutting. 

Benefits of Zero-Waste Sewing Patterns

It reduces waste in the fashion industry.

The fashion industry is one of the major polluters in the global industry. Garment making produces textile waste at all stages, during construction and after the consumer uses the clothes. We know this as pre-consumer and post-consumer waste. 

However, most waste reduction efforts have been directed towards the post-consumer waste stage. Zero-waste patterns help tackle waste at its initial stage instead of waiting until the post-consumer stage. They reduce fabric waste, which, in turn, helps save resources. It also reduces paper waste.  

Designers and manufacturers do not have to use as much fabric to produce clothes. The reduced fabric uses fewer resources, such as chemicals, energy, and water. Using zero-waste pattern design combined with other sustainable fashion techniques reduces the amount of textile waste in landfills.

It saves time.

The zero-waste concept in pattern cutting also saves time spent on designing and sewing garments. With the conventional pattern-cutting technique, a dress with 20 pattern pieces takes longer than one with 10 pieces. However, zero-waste methods are quicker. A dress with 20 pattern pieces is faster to cut than the conventional pattern. 

It reduces design costs.

Another benefit of ZWPC is the reduction in design costs. Designers do not need to use as much fabric as they do with conventional sewing methods because zero-waste saves fabric. So, they don't spend much money buying textiles and other materials that make the fabric wearable. 

Limits of Zero-Waste Pattern Cutting

As much as ZWPC holds great possibilities for the fashion industry, it still has limitations. Some of them are: 

1. Sketching zero-waste designs is challenging because most designers do not know how to describe their construction methods.

 2. Another issue is that some designers can only imagine fabrics within a two-dimensional structure. They think of fabrics along a solitary visual plane, which presents as a hanging curtain or a three-dimensional shape like a shirt or chair cover. This problem is because ZWPC requires a subtle connection between 2-D patterns and 3-D structures.

3. Also, designers have to reduce their aesthetic control when designing zero-waste apparel. With ZWPC, they must create commercially feasible and appealing clothing that balances modern styles. It might be a problem for some designers because consumers prefer unique aesthetics.

4. Zero-waste cutting presents a creativity problem for mass production. It has yet to gain widespread recognition, but designers need to produce it on a large scale across various sizes for it to do so. Research has identified this challenge and a suitable solution has yet to be found².

Conclusion  

There are many ways to foster sustainability in the fashion industry. Although it might be challenging to implement zero waste pattern cutting globally with big manufacturers, small designers can start implementing it in their designs. 

There are zero-waster pattern design courses you can explore as a designer. So, create clever sleeve hem patterns and decorate with unique patch pockets. Save the planet one step at a time.
