Thick plastic stretchy cord is a versatile material that can be used to create unique designs for jewellery and other craft projects. It is a popular choice among crafters due to its strength, durability, and ability to stretch. When working with thick plastic stretchy cord, it is important to consider the weight and size of the beads or other materials being used, as well as the technique for securing the cord to prevent unravelling. Various methods for securing the cord include pre-stretching, double knotting, and using glue or nail polish to reinforce the knot.

What You'll Learn
Use a reliable knot like the surgeon's knot
Using a reliable knot, such as the surgeon's knot, is a simple and effective way to secure thick, plastic, stretchy cord. This knot is ideal for jewellery-making, especially stretch bracelets, as it prevents the cord from loosening or becoming baggy over time.
To tie a surgeon's knot, start by bringing the two ends of the cord together, crossing one cord over the other. Form a half knot by wrapping the front cord over and around the back cord, then bring it back to the front. This initial half knot will keep your beads in place as you continue.
Next, form the two cord ends into a circle, with one crossing in front of the other. Create another half knot by repeating the previous step: wrap the front cord over and around the back cord. Now, wrap it around a second time.
Pull the knot tight by tugging on the cord ends and beaded ends in a specific sequence: first, pull both cord ends, then pull the two beaded ends. Finally, pull one cord end and the opposite beaded end, repeating on the other side.
To further reinforce the surgeon's knot, you can apply a small amount of GS-Hypo Cement or clear nail polish. These adhesives will enhance the knot's security, ensuring it doesn't come undone with wear.

Add glue to the knot
Adding glue to the knot of a thick plastic stretchy cord is a great way to ensure that your knot stays secure. There are several types of glue that can be used for this purpose, each with its own advantages. Here is a step-by-step guide on how to add glue to the knot effectively:
Choosing the Right Glue
Select a glue that is suitable for use with elastic cords and jewellery making. Some recommended options include:
- E6000 Adhesive: This glue is clear, flexible, and waterproof. It is easy to apply and can be found at most craft stores.
- Special T Glue: Designed to fill gaps inside knots, making them more secure. It dries pliable rather than hard and takes about 60 seconds to dry.
- G-S Hypo Cement: An all-purpose glue that can be used on various surfaces like glass, plastic, metal, and wood. It sets in 10 minutes, dries in an hour, and cures completely within 24 hours.
- Cement Glue: Recommended for jewellery making due to its precision application. It has a fine nozzle, making it ideal for intricate work.
Applying the Glue
Once you have selected your glue, follow these steps:
- Tie your knot securely, pulling tightly from all directions to ensure it is tight. A surgeon's knot or a simple overhand knot are good options.
- Use a toothpick or a headpin to apply a small amount of glue to the knot.
- Allow the glue to dry completely before wearing your jewellery. This may take some time, depending on the type of glue used.
- Trim off any excess cord using scissors or side cutters.
Tips and Tricks
- Avoid using super glue as it can become brittle over time and may corrode the elastic.
- Store your elastic cord away from direct sunlight and warmth to maintain its strength.
- Consider using a thicker cord, as they are generally easier to work with and provide a more secure knot.
- If you're having trouble pulling the cord tight enough, use pliers to get a secure grip.
- Cover your knot by hiding it inside a bead or using spacers with large holes to improve the overall look and protect the knot from wear.

Use two cords for added durability
When securing thick, plastic, stretchy cord, using two cords instead of one can greatly increase the durability of your design. This technique is especially useful if you are stringing gemstones or other chunky, abrasive beads, as these can tear into the elastic cord.
To begin, cut a piece of cord that is the circumference of your wrist, plus at least three extra inches of elastic on each side for tying knots. Remember that this type of cord is slippery, so having extra length will prevent the cord from slipping out of your hands during the process.
After pre-stretching your cords, thread your beads onto both strands simultaneously, ensuring that they fit inside the bead channels. It is important to pre-stretch your cords to loosen them up and prevent your design from stretching and distorting over time. Once you have added your beads, tie a simple overhand knot by crossing the strands over and folding one end under the other to create a loose knot.
To finish, pull the knot tight and consider applying a small amount of glue to the knot to ensure it stays secure. You can use super glue or a specialised jewellery glue like E6000, which stays flexible and is less likely to erode the elastic. Allow the glue to dry completely before trimming the excess cord.
By following these steps and using two cords, you can create a much more durable piece of jewellery that will last longer and be less likely to break.

Pre-stretch the cord to avoid lengthening
Pre-stretching your elastic cord is a crucial step in ensuring the quality and longevity of your jewellery. Elastic cords have a natural tendency to stretch over time, especially when they are constantly being put on and taken off. By pre-stretching, you can prevent excessive elongation and maintain the original fit of your bracelet.
To pre-stretch your cord, start by cutting a length of elastic cord that's slightly longer than what you'll need. Hold each end of the cord firmly and gently pull it to stretch it out, being careful not to overstretch or snap it. Repeat this process several times to ensure the cord is fully extended. This step will help you achieve a consistent tension when stringing your beads, resulting in a neat and professional appearance.
Pre-stretching can also help identify any weak areas or defects in your cord that might lead to breakage. By addressing these issues early on, you can enhance the durability of your jewellery. Additionally, pre-stretching eliminates any "give" that might occur after completing your bracelet, ensuring that it retains its shape and size without loosening over time.
After pre-stretching, your cord will retain its elasticity but will be less prone to lengthening. This will help your jewellery maintain its intended design and drape. To further secure your bracelet, consider using two cords instead of one. This will make your jewellery feel more solid and steady.
When working with elastic cord, it is essential to use the right type of glue to secure your knots. Special T Glue and G-S Hypo Cement are recommended for their strength and compatibility with various materials, including plastic. Avoid using super glue as it can corrode the elastic over time.

Avoid using crimps
When securing thick plastic stretchy cord, it is recommended to avoid using crimps. Crimps can potentially cut and damage the elastic cord, ruining your hard work. The thicker the elastic cord, the more challenging it is to work with. Here are some alternative methods to secure your cord without using crimps:
Firstly, select the right type of cord. Stretch Magic is a popular choice for jewellery makers as it is strong, stretchy, and durable. It won't crack or harden over time and doesn't require a clasp. Before you begin, pre-stretch your cord to loosen it up and prevent your design from distorting.
Secondly, tie a secure knot. A simple overhand knot or a double overhand knot is recommended by manufacturers to ensure your design is secure. When tying the knot, pull the elastic taut and stretched to add tension, which will help keep the knot from untying. The surgeon's knot, a type of square knot, is also recommended as it has an extra loop that prevents slipping.
Finally, reinforce the knot with glue. Apply a small amount of super glue or E6000 jewellery glue to the knot to ensure it stays in place. You can also use clear nail polish as a substitute for glue. Allow the adhesive to dry before trimming any excess cord.
By following these steps and avoiding the use of crimps, you can securely fasten thick plastic stretchy cord for your jewellery-making projects.
