What You'll Learn
Let the paint dry for at least 24 hours before heat-setting
When painting fabric, it's important to let the paint dry before heat-setting it. This is because the paint needs to be completely dry to prevent ink bleeding onto the fabric during the heat-setting process. If the paint is not dry, you may ruin your fabric. Therefore, it is recommended that you let your fabric air-dry for at least 24 hours before heat-setting it. If you have painted the fabric thickly, you may even want to wait longer than 24 hours. To check if the paint is dry, you can slightly touch the painted area to see if there is any paint left. If there is none, you can begin the heat-setting process.
The heat-setting process involves applying heat to the painted fabric to help the resin bind to the cloth and stay there permanently. This can be done in several ways, including using an iron, a clothes dryer, or an oven. If you are using an iron, it is recommended to use a dry heat setting and place a scrap cloth between the iron and the painted fabric to prevent the paint from burning. You can also use a piece of paper between the iron and the fabric to prevent the paint from dying the other side of the fabric. Set your iron to the appropriate temperature for your fabric, and iron the painted area for about 2 to 5 minutes.
If you are using a clothes dryer, set it to the highest temperature and leave the fabric in for about an hour. This method is convenient because you don't need to prepare anything other than the painted fabric and the dryer. For an oven, preheat it to 350℉ or 176℃ and place the painted fabric inside for 2 to 3 minutes. It is important to note that you should not wash the fabric for at least four days after heat-setting to allow the paint to set properly.

Use an iron as a heat source for heat-setting
Using an iron as a heat source for heat-setting fabric marker painted cloth is a popular technique. It is also possible to use an oven or a dryer for this purpose. However, using a high-temperature iron can be dangerous and may cause severe burns. It is recommended to keep the iron moving to prevent scorching.
Before using an iron, make sure the painted fabric is completely dry. This usually takes at least 24 hours, but it is recommended to wait longer if the paint has been applied thickly. Turn off the steam setting and set the iron to the highest temperature suitable for the fabric. If the fabric is delicate, use a lower temperature and iron for longer. Place a piece of paper or a thin cloth between the painted surface and the iron to prevent the paint from sticking to the iron.
Iron the fabric for at least two minutes, but ideally more. Golden Paints recommends ironing "for 3-5 minutes with a medium-hot iron on the reverse side." If the fabric is large, reposition the scrap cloth or paper and repeat the process until the entire painted area is heated. After heat-setting, do not wash the fabric for at least four days. Wash the fabric with cold water the first few times to prevent colour bleeding.

Place a sheet of paper or cloth between the iron and the painted surface
When heat-setting fabric markers, it is important to place a sheet of paper or cloth between the iron and the painted surface. This is to prevent the fabric paint from interacting directly with the heat source and burning. The paper acts as a partition, and a scrap cloth can be used as an alternative. This is also to protect your iron from any transfer of colour and to prevent accidentally scorching the painted side of the fabric.
It is important to wait until the paint on your cloth is completely dry before heat-setting. You should wait at least 24 hours, and longer if you have painted the fabric thickly. You can test if the paint is dry by slightly touching the painted area to check if there is any paint left.
Once the paint is dry, set your iron to 350℉ or approximately 176℃, and let it heat up. Make sure to turn off the steam setting and use dry heat to set the fabric paint. Using steam or water will cause ink bleeding. Adjust the heat according to the type of fabric you are using. For example, if you are working with delicate fabric such as silk, you should lower the heat.
Place your product onto the ironing board. If possible, iron on the "wrong" side of the fabric and not the painted side. You can place a scrap piece of fabric over the top of the painting to protect the painted side. Set the iron on a medium to hot setting, determined by the type of fabric. Run the iron across the painted area for a few minutes, moving it around constantly so you don't scorch the fabric. If it is a delicate material, set the iron to a lower temperature and iron for longer to properly heat-set the fabric paint.
After heat-setting, remove the paper or scrap cloth and let the fabric dry completely. Do not touch the painted area during this time. Wait at least four more days to put your clothes in the laundry. Wash your fabric with cold water the first few times to make sure the colours do not bleed.

Iron for 4-5 minutes, gliding continually
To heat-set fabric markers or fabric paint, you must apply heat to the painted fabric to help the resin bind into the cloth fibers and stay there permanently. This process is called heat setting and is a vital step to prevent ink from bleeding, running, or fading and damaging your products during the first laundry.
The most popular technique for heat setting is to use an iron as a heat source. Before ironing, ensure that the paint on your cloth is completely dry. At a minimum, wait 24 hours, and longer if you've painted it on thickly. You can test whether the paint is dry by slightly touching the painted area to check if there is any paint left.
Once the paint is dry, turn the clothing inside out and place it onto the ironing board. Preheat your iron to the maximum temperature safe for the fabric. Place a sheet of paper or a thin cloth over the marker design to prevent the fabric paint from interacting directly with the heat source and burning. Set the iron to a cotton heat setting without steam.
Now, glide the iron back and forth continually over the area for four to five minutes. If you are using a press cloth, you may want to iron the front side of the fabric. Otherwise, place a clean, dry cloth over the front of the design and iron for 4-5 minutes. If you have a large design, you may need to iron in sections. Remove the paper or cloth and allow the fabric to cool completely. Repeat the same process until you have ironed every area of the design.
Finally, turn the fabric right side out and allow it to cool completely. After heat-setting, it is recommended to wait at least four days before washing the fabric.

Do not wash the fabric for at least 4 days after heat-setting
When it comes to fabric markers and paint, heat setting is an essential step to ensure the ink binds to the cloth and doesn't bleed or damage your creation during the first wash. This process involves applying heat to the painted fabric, typically through ironing, oven baking, or using a clothes dryer. While you might be eager to finish your project, it's crucial to wait at least four days after heat-setting before washing the fabric. Here's why:
Firstly, allowing the paint to dry thoroughly before heat-setting is vital. Most sources recommend waiting at least 24 hours, but this duration may vary depending on the thickness of the paint application. It's important to ensure the paint is completely dry to avoid any unwanted smudging or smearing during the heat-setting process.
Secondly, the heat-setting process itself requires time to properly activate the paint's binding properties. Different types of paint may have specific instructions, with some recommending up to 10 to 14 days of curing time after heat-setting. Always refer to the manufacturer's instructions for the paint you are using.
Additionally, the waiting period allows for any potential issues with the paint application to become apparent. For example, you might notice that the paint hasn't fully adhered to the fabric or that there are areas where the colour is uneven. By waiting a few days, you can identify any problems and make necessary adjustments before washing.
Moreover, the curing time ensures the durability of your design. Rushing the process by washing too soon might cause the paint to crack, fade, or wash out, undoing all your hard work. Giving the paint ample time to set helps ensure that your design will withstand the wear and tear of regular use and laundry.
Lastly, different fabrics have varying heat tolerances and care requirements. By waiting a few days, you can test the fabric's reaction to the paint and heat-setting process. This way, you can ensure that the fabric remains intact and doesn't shrink, distort, or discolour due to the paint or heat application.
