Shrinking plastic is a fun and simple activity that can be done by people of all ages. It involves taking a thin sheet of plastic, commonly known as Shrinky Dinks, and using heat to shrink it down to half its size. The process is entertaining to watch, as the plastic curls and then flattens out to create a unique, miniature version of your original sheet. This craft is a great way to make personalised gifts, such as charms, jewellery, and shaped pieces. To get started, you'll need a heat source, such as an oven or heat gun, and a sheet of plastic with the triangle recycling symbol and a #6 rating. Once you've gathered your materials, you can begin the process of shrinking your plastic miniature!

Use a toaster oven, a regular oven, a heat gun, or an embossing heat tool
To shrink a plastic miniature, you can use a toaster oven, a regular oven, a heat gun, or an embossing heat tool. Each of these methods involves heating the plastic to a high temperature, causing it to shrink. Here is some more information on each method:
Toaster Oven
A toaster oven is a miniature oven that functions similarly to a standard oven. To use a toaster oven to shrink plastic, you will need a baking tray. Place your plastic miniature on the tray, following any specific instructions that came with your product. Heat the oven to between 350 and 375 degrees Fahrenheit. Keep in mind that your plastic may begin to curl as it heats up, but this is normal, and it will flatten back out. If the edges touch and stick together, gently pry them apart with pliers or forks, then return the plastic to the oven. Once your plastic has flattened out again, it is done. Remove it from the oven and allow it to cool.
Regular Oven
Using a regular oven is similar to the toaster oven method. Place your plastic miniature on a baking tray and follow any specific instructions. Heat your oven to the recommended temperature and keep an eye on your plastic as it may begin to curl and then flatten out. If the edges stick together, gently pry them apart and return the plastic to the oven. Once it has flattened out again, remove it from the oven and allow it to cool.
Heat Gun
A heat gun can be used to shrink plastic miniatures, but it requires careful handling. Direct the heat gun at your plastic miniature, being mindful not to get too close or hold the heat in one spot for too long, as this could damage your plastic. Move the heat gun in a rhythmic, wafting motion to evenly heat the plastic and cause it to shrink.
Embossing Heat Tool
An embossing heat tool can also be used to shrink plastic. This tool is designed to heat specific areas of a material, so it can be useful for shrinking plastic miniatures without affecting the surrounding area. Follow the instructions for your particular tool, being mindful of the heat settings and the distance from the plastic to avoid any damage.

Prepare the plastic sheet by roughening it with sandpaper
To prepare a plastic sheet for shrinking into a miniature, you need to first source a suitable sandpaper. You can buy fine-grit sandpaper at any home repair or crafting store. A 360, 400, or 600-grit sanding block or sandpaper is ideal for this purpose. Once you have your sandpaper, the next step is to gently roughen the surface of the plastic sheet. Rub the sandpaper over the entire surface of the plastic sheet, scratching it up to create a texture that paint can cling to. This process is important as it ensures that the paint will adhere properly to the plastic surface. It is recommended to use light pressure to avoid weakening or damaging the plastic sheet.
After you have finished roughening the surface, it is important to remove any loose bits of sanding or dust from the sheet. Hold the sheet under a sink or hose to wash away the dust and sand. You can also use a towel to wipe away any excess moisture. Once the sheet is dry, you can place it near a fan or in a well-ventilated area to speed up the drying process. This step is crucial as any remaining dust or moisture can affect the quality of your paint job.
It is worth noting that the purpose of roughening the plastic sheet is to create a surface that can be coloured effectively. The roughened surface allows you to use a variety of colouring materials, such as pencils, felt-tip pens, or permanent markers. This process is especially useful if you are using a clear, smooth, or crystal-clear plastic sheet, as it provides a better surface for the colour to adhere to.
Additionally, when colouring the roughened surface, it is important to keep in mind that the colour will intensify as the plastic shrinks. Therefore, it is recommended to apply the colour lightly as it will become more concentrated after shrinking. Using light shades of pencils or other light-coloured materials is generally advisable, as the colour will darken during the shrinking process. Neatness is not a priority during colouring, as you will cut out the image, and the shrinking process will concentrate the colour.

Use colouring pencils, permanent markers, or stamp ink to add colour
When using colouring pencils, permanent markers, or stamp ink to add colour to your plastic miniature, there are a few things to keep in mind. Firstly, if you're using colouring pencils, you may need to prime the surface of the plastic with a light coat of paint or primer to create a better surface for the pencil lead to adhere to. Permanent markers, on the other hand, can be used directly on the plastic surface. Copic markers, in particular, are popular for colouring plastic as they are filled with permanent alcohol inks that work on a variety of surfaces, including plastic. You can also refill your markers with the same ink, which is convenient for consistent colouring.
If you want to add colour with stamp ink, the type of ink you choose is important. Some inks may be too thin and not stick to the plastic, while others may be too thick and get into the engraving of a stamp. Solvent ink is recommended for printing on plastic surfaces. You can also try using pigment ink, such as the Faber-Castell Ecco Pigment markers, but be aware that this type of ink may have trouble drying properly on hard plastic.
When colouring with markers directly on the plastic, be aware that the marker may streak. To avoid this, work quickly and avoid layering too much ink. Thin layers of ink will dry after a minute or so, but dense areas will need longer to dry. Keep an eye out for dense ink spots, as they may not dry completely and become sticky. If you make a mistake or want to lighten a dark area, you can use rubbing alcohol or hand sanitiser to remove the ink.
Additionally, keep in mind that dark colours will show up better than light colours on glossy surfaces. If you're using a light-coloured marker, you may need to drip ink directly onto the surface instead of colouring with the marker to achieve the desired effect. Overall, take your time and experiment with different colours and techniques to achieve the desired look for your plastic miniature.

Keep the colour light as it will darken when the plastic is shrunk
Shrinky Dinks, a popular brand in the 80s, introduced thin plastic sheets that could be coloured in and shrunk down with heat to become thicker and more rigid. This process of shrinking plastic is almost magical and produces elegant and sophisticated results.
When colouring in these plastic sheets, it is important to keep the colours light as the shrinking process will cause the colours to intensify and darken. The concentration of colours after shrinking can be quite stark, so it is best to use light shades of colouring pencils, felt-tip pens, or permanent markers.
If you are using a clear, smooth plastic sheet, you can use sandpaper to roughen the surface and make it more suitable for colouring with pencils. Alternatively, you can use permanent markers on the smooth surface. The best results are achieved when using contrasting colours that create a wow factor once the plastic is shrunk.
It is also important to note that the more detailed the design, the messier it will look when shrunk. Simple designs and solid colours tend to work better. Additionally, it is recommended to cut out the desired shape before shrinking, as cutting the delicate shrunk plastic can be challenging.

Display your shrunk plastic miniature as a keychain, earring, or magnet
Shrink plastic is a versatile material that can be used to create unique and personalised keychains, earrings, or magnets. Here are some detailed instructions for each:
Keychains
You can design and create a keychain using shrink plastic sheets, markers, colour pens, and other craft supplies. Start by drawing or tracing your desired design onto the shrink plastic. If you're using a template, print it out and customise it to your liking. Remember to make the design bigger than your desired size, as the plastic will shrink. You can also add quotes or sayings to your keychain. After finalising your design, bake the plastic in the oven for a few minutes, following the manufacturer's recommendations, until it shrinks and flattens. Once removed from the oven, place a weight on top until it hardens. If it's still pliable, reheat it. Finally, attach a jump ring and connect your keychain to a key ring.
Earrings
To make earrings, you can use white, black, or clear shrink plastic sheets. Experiment with different colours and print designs onto the sheets. Ensure the rough side of the plastic is up when printing to avoid smudging. The colours will darken during the heating process, so keep that in mind when choosing your palette. Cut out your earring shapes and punch holes in them. Use a hot gun to heat the plastic, and don't worry if it twists—this is normal. Once it's shrunk, let it cool, and if it's not completely flat, use a smooth object to gently flatten it. Apply a coat of sealant to protect your design and add durability. Finally, attach jump rings and earring wires to complete your handmade earrings.
Magnets
Start by sketching out your magnet designs on paper. Remember to make them larger than your desired size to account for shrinkage. Place a sheet of shrink plastic over your sketch and trace the design onto the plastic. Colour in your design using mediums such as coloured pencils, avoiding water-soluble markers. Cut out your shapes neatly, as the edges will harden during shrinking. Bake the plastic in the oven until it shrinks and flattens. Once cooled, apply a protective coat to preserve the colours. Finally, attach magnets to the back of your designs using hot glue, and your shrink plastic magnets are ready!
