Shrink plastic earrings are a fun craft project that can be made at home. The process involves cutting shrink plastic into earring shapes, punching holes for earring hooks, and then heating the plastic to shrink it. This can be done using an oven or a heat gun. The colours of the earrings will darken and intensify during the heating process, so it is important to choose light colours to start with if you want less intense colours in the final product. After shrinking, the plastic can be flattened with a plate and then jump rings and earring hooks are added to the holes. The earrings can be made glossy by using a brush-on varnish or resin.

What You'll Learn
Cutting out the earring shape
Firstly, decide on the desired shape for your earrings. You can choose from a variety of options, such as flowers, angel wings, or any custom design you prefer. Once you have your design ready, use regular scissors to cut around the outline of each earring shape. Shrinky Dink sheets or shrink plastic sheets are relatively easy to cut, and you can also use a handheld rotary device for more intricate cuts. Ensure that you cut smoothly and avoid leaving any sharp edges on the plastic.
When cutting out the shape, it is essential to consider the placement of the holes for the earring hooks. Mark the spots where you plan to punch holes, typically at the top or on the sides of the earring design. These holes will be used to attach the jewellery findings or earring wires later on. Remember to punch the holes before cutting out the shape, as it will be challenging to do so once the plastic has been shrunk.
If you are creating intricate or detailed earring shapes, you might want to print or draw your designs onto the plastic sheets before cutting. You can use tracing paper to copy your designs or draw them freehand. Go over the outlines with a thick black marker or Sharpie, then colour in the rest of the designs as desired. You can also experiment with different colours of shrink plastic, such as white, black, clear, or frosted varieties, to achieve the desired background for your earrings.
Once you have cut out the earring shapes, it's time to move on to the next step of shrinking the plastic. Remember that the colours may darken and intensify during the heating process, so choose your colours accordingly. Additionally, always refer to the manufacturer's instructions for specific guidelines on heating and shrinking the plastic.

Punching a hole for hooks
To begin, use a standard hole punch or a regular-sized hole punch, which is typically around 1/8" in size. Punch a hole in the desired location, considering where you will attach the jewellery fastenings later. You can experiment with different hole sizes and locations to see what works best for your design. Mark the holes to keep track of the different sizes. Remember that the hole will shrink along with the plastic, so plan accordingly.
If you forget to punch a hole before shrinking, you can use a handheld rotary device or a drill to create the hole afterward. However, it is much easier to punch the hole when the plastic is still in its original, larger format.
Once you have punched the holes, you can proceed to the next steps of shrinking the plastic and adding the jewellery findings or earring wires to create your unique handmade earrings.

Baking the earrings
Before placing the plastic in the oven, ensure that you have followed the previous steps, including punching a hole in the plastic where the earring hooks will attach. Then, place the plastic shapes face-up on a baking tray lined with parchment paper, ensuring they are not touching. Heat the oven to the recommended temperature and place the tray inside.
As the plastic heats up, it will start to curl and then flatten. If the plastic struggles to flatten on its own, you can place a plate over it for a few seconds to help it along. Use pliers to attach a jump ring and earring hook to the hole in each shape after they have cooled.
If you want to add a glossy finish to your earrings, you can use a brush-on gloss varnish or resin. You can also use a sealant to make your earrings more durable and long-lasting. Spray sealants are a good option, and you can even find ones with a glossy finish.
Remember that the colours of your earrings will darken during the baking process, so choose your colours accordingly. It is always a good idea to do a test run with a small piece of plastic to ensure that the colours come out as expected.

Flattening the earrings
Preparing the Plastic Sheets
Before flattening, you must first prepare your plastic sheets by punching holes where the earring hooks will attach. This step is important as it ensures the earrings can be worn. Then, place the plastic shapes face-up on parchment paper, ensuring they do not touch. This preparation sets the foundation for the flattening process.
Baking the Plastic Sheets
The next step is to bake the plastic sheets in the oven. Preheat your oven to the temperature specified in the instructions provided with your chosen plastic. Typically, temperatures range from 150°C to 170°C, but it's important to refer to your specific instructions. Place the tray with the plastic shapes into the oven for 2-3 minutes. During this time, you will witness the magic of the plastic shapes curling up and then flattening. This transformation is a result of the heat activating the shrinking properties of the plastic.
Flattening Techniques
If your plastic shapes struggle to flatten completely after removing them from the oven, there are a few techniques you can employ:
- Place a Plate on Top: Place the warm plastic shapes under a plate for a few seconds. The gentle pressure from the plate will help guide them into a flat position as they cool.
- Lightly Tap with a Smooth Object: If there are slight imperfections or wavy areas, use a smooth and flat object to lightly tap the plastic before it cools completely. This gentle force will nudge it into a flatter shape.
- Adjust Timing: Depending on your plastic type, you can experiment with leaving the plastic in the oven a little longer. Sometimes, allowing it to bake for an additional minute can help it flatten further.
Finalizing the Earrings
Once your plastic shapes have cooled and flattened, it's time to assemble the earrings. Using pliers, attach a jump ring to an earring hook, and then insert the assembly into the hole of each plastic shape. This final step transforms your flattened plastic shapes into wearable earrings.
By following these detailed steps for flattening the earrings, you can ensure your shrink plastic earrings turn out beautifully and are comfortable to wear.

Adding hooks and jump rings
There are a variety of sealants that can be used, such as a spray sealant or a liquid sealant like Glossy Highlights. You can also use a brush-on gloss varnish or resin to add a shiny, polished look to your earrings. If you use resin, you will need to mix the two parts in a plastic cup with a stirrer and let it set for eight minutes to release any gas bubbles. Then, use a chopstick to carefully add a drop of resin to the top of each earring and let them set for at least eight hours.
The process of adding hooks and jump rings is straightforward, but it is important to take your time and be careful not to make any marks on the plastic. With the right tools and a little patience, you can create unique and personalized earrings that are both durable and stylish.
