Sewing plastic can be a challenging task due to its slippery nature. However, with the right tools and techniques, it is possible to sew plastic without slipping. This involves using the correct type of plastic, such as sewable 100% PVC (polyvinyl chloride), and preparing the plastic before sewing by using clips instead of pins to avoid permanent holes. Additionally, it is recommended to use a Teflon foot or a non-stick needle to prevent the plastic from sticking to the sewing machine. Other tips include adjusting the thread tension and stitch length, using tissue paper or parchment paper, and practicing on scraps before sewing the final product.

What You'll Learn
Use regular/sew-all polyester thread
When sewing plastic, using regular/sew-all polyester thread is a good option. Polyester thread is strong and durable, and it can be used for a variety of projects, from quilting to sewing delicate fabrics. It is also suitable for both hand and machine sewing. Here are some tips for using regular/sew-all polyester thread when sewing plastic:
Choose the Right Type of Polyester Thread
Select a polyester thread that matches the elasticity of the plastic you are sewing. Universal sew-all polyester thread is a good option for beginners as it is easier to work with than invisible thread. Polyester thread comes in different colours, so choose one that matches your fabric. Clear polyester thread is also available and can be used when you don't have the right colour thread on hand or when sewing multicoloured fabrics.
Prepare the Thread and Plastic
Before sewing, wind your bobbin slowly and set your machine to a slow, even pace to avoid generating friction and heat, which can cause the thread to stretch. Iron the plastic with a synthetic setting to remove any creases. If any creases cannot be removed, cut them away. Wash the plastic with cool water beforehand to remove any coatings and colourings.
Use the Correct Needle
Polyester thread should be used with a fresh, sharp, or microtex needle in a size 8. If you are using a sewing machine, set it to a ballpoint needle to reduce the likelihood of damaging the fibres of the plastic. Make sure the pressure on the sewing machine's foot is as low as possible to avoid puckering.
Stitching Technique
When stitching, use small, narrow zig-zag stitches on the seam. Lay the pieces cross-grain rather than lengthwise. If using invisible thread, lock your stitches by backstitching at the beginning and end of each seam to prevent them from pulling free. Test your stitches before starting your project.
Avoid Slipping
To avoid slipping when using regular thread, use tissue or computer paper as a stable backing. This will prevent the plastic from sliding under the needle.

Use a brand new sharp needle
Sewing plastic requires puncturing the material, and a brand new sharp needle is essential for this process. A dull needle can cause issues with timing and lead to skipped stitches. Therefore, it is important to start with a sharp needle to ensure smooth stitching and avoid any potential snags or tears in the plastic.
Using a new needle will also help to create clean holes in the plastic. As plastic will retain permanent holes, it is crucial to get the tension and stitch length right before beginning. Practicing on scrap pieces of plastic can help with this, allowing you to perfect your technique without risking damage to your final product.
Additionally, the thickness of the plastic should be considered when selecting a needle. Thicker plastics may require a larger needle to penetrate the material effectively. However, it is important to note that using a thicker thread can also increase friction, so finding the right balance is key.
By using a brand new sharp needle, you can achieve precise and consistent stitching when sewing plastic. This simple step can greatly improve the overall quality and appearance of your project, ensuring a smooth and professional finish.
Lastly, it is worth mentioning that proper needle selection is crucial for successful plastic sewing projects. Along with choosing a new sharp needle, it is important to consider the needle size and type that best suits the thickness and nature of the plastic you are working with. This includes taking into account factors such as needle point type, needle eye size, and needle material, all of which can impact your stitching experience and results.

Use clips to hold vinyl together
Sewing vinyl can be challenging due to its tendency to stick to the presser foot and needle plate. It is also unforgiving, as any stitches that need to be removed will leave holes in the material. It is essential to use a sharp, brand-new needle when sewing vinyl because puncturing the plastic with a dull needle can lead to skipped stitches.
When sewing vinyl, it is recommended to use clips instead of pins to hold the layers together. Pins will leave permanent holes in the vinyl, whereas clips will not. Clover Clips, binder clips, paper clips, and even bobby pins can all be used to hold vinyl together. However, it is important not to leave the clips on the vinyl for too long, as they can leave permanent indentations.
When preparing to sew vinyl, it is important to remove any creases and ensure that the vinyl is flat. Hanging the vinyl on a clothesline is a good way to straighten it out. It is also important to note that vinyl should not be ironed directly, as this will melt the plastic and leave permanent marks. Instead, use a pressing cloth with light and quick presses, or hover the iron above the vinyl to smooth out any deep creases.

Don't directly iron onto vinyl
When preparing to sew vinyl, it is important to iron out any creases and wrinkles to ensure a smooth surface. However, directly ironing onto vinyl is not recommended as it will melt and leave permanent marks on the plastic. Instead, use a pressing cloth, such as a scrap of fabric or a towel, between the iron and the vinyl to protect the fabric from melting. It is also important to use a low-heat iron and ensure the vinyl is lying completely flat before you start ironing.
If you are looking to remove deep creases, you can hover the iron above the vinyl or use quick, light presses with a pressing cloth. A heat gun or a hair dryer on a low setting can also be used to remove creases and wrinkles. It is important to avoid using steam as this will only get the vinyl wet. Additionally, make sure that you do not have multiple layers of vinyl directly touching each other when applying heat, as they can melt together.
When ironing a finished project, such as a bag, you can place the item on a pressing mat or a warm cotton mat and then put it face down. This will help to remove wrinkles without needing to directly iron the vinyl.

Use a Teflon foot or plastic bag
Using a Teflon foot or a plastic bag are both great options for sewing plastic without slipping. A Teflon foot is a non-stick foot that is compatible with 7mm and 9mm machines. It is also available for the Janome 1600P straight stitch machine. The Teflon foot glides over the plastic without sticking, making the sewing process easier and smoother. It is important to note that you should use a new, sharp needle when sewing plastic, as a dull needle can affect timing and cause skipped stitches. Additionally, you should lengthen your stitch to prevent the plastic edge from tearing.
If you don't have a Teflon foot, you can use a regular foot with a plastic bag or tape underneath to prevent sticking. This method may be more cumbersome as it can be hard to see where you are sewing. Another option is to use a roller foot, which feeds vinyl through your machine well.
It is recommended to practice sewing on scrap fabric first, as vinyl will leave permanent holes. You should also avoid using pins, as they create holes that won't go away. Instead, use Clover Wonder clips or scotch tape to hold the layers together. Keeping the room cool can also help prevent the plastic from sticking together.
