What You'll Learn
Prepare the fabric and letters
To prepare the fabric, start by selecting a suitable material. Cotton fabric is recommended as it provides a smooth surface for the letters to adhere to properly. If using a coloured fabric, it is ideal to pre-wash and iron it to remove any wrinkles or substances that might interfere with the adhesion of the iron-on letters. Once dry, set your iron to the correct temperature for the fabric. For cotton, a medium-high setting is recommended, typically the ''cotton'' setting, and ensure the steam function is deactivated.
Next, place your fabric on a flat, hard, and heat-resistant surface, such as a wood cutting board, to avoid any wrinkles that could distort the placement of the letters. You can lay a sheet, pillowcase, or tissue paper on top of the hard surface before placing your fabric. Make sure to iron the fabric to remove any wrinkles before applying the letters.
Now, carefully cut out the individual letters that you will be using. Mirror the letters to ensure they appear correctly on your fabric. Position the letters where you want them, with the adhesive side down, and check for proper alignment. Use a ruler to ensure straight wording.
Once you are happy with the placement, cover the letters with a protective layer, such as parchment paper, a thin cloth, or the tissue paper that may have come with the letters, to shield the plastic from the heat of the iron.

Use the right iron settings
Using the right iron settings is crucial when applying iron-on letters to ensure they adhere properly and look great. Here are some detailed instructions to guide you through the process:
Firstly, select the right fabric for optimal adhesion. Cotton fabric, especially 100% cotton, is highly recommended as it provides a smooth surface for the letters to adhere properly without damage. If you can't find a 100% cotton fabric, opt for one with the highest percentage of cotton available.
Before you begin, prepare your fabric by washing and ironing it, especially if it's a coloured fabric. This step helps to remove any wrinkles or substances that might interfere with the adhesion of the iron-on letters. Make sure to avoid using fabric softener or softener sheets in the dryer as they can leave a chemical coating that interferes with the transfer glue.
Now, let's set up your iron. Preheat your iron to the "cotton" setting, which is typically a medium-high temperature. It's important to turn off the steam function as using steam can prevent a complete seal. Allow the iron to warm up for at least 8 minutes.
When you're ready to apply the letters, place them face down on your fabric with the adhesive side down, ensuring they are spelled correctly and aligned properly. Cover the letters with a protective layer, such as parchment paper, a thin cloth, or tissue paper, to shield the plastic from the heat.
Firmly press the heated iron onto each letter, working from the middle to the outside edges to avoid air bubbles. Apply firm pressure for 20-50 seconds. If you're right-handed, work from right to left and top to bottom.
After ironing each letter, run the iron over all the letters again, paying close attention to the corners and edges to ensure they adhere securely.

Position the letters
Positioning your iron-on letters correctly is key to achieving a neat and professional finish. Here are some detailed instructions to guide you through the process:
Firstly, prepare your work area by laying a sheet or pillowcase (folded in half) on a hard, flat surface. This will provide a smooth base for your fabric, ensuring there are no wrinkles that could distort the placement of your letters. Place your fabric on the prepared surface, with the front side facing up.
Now, it's time to position the letters. Carefully cut out each individual letter, ensuring that the margins around each one are uniform. This consistency in margins will help you line up the letters evenly. A scant 1/8th inch of space around each letter is a good guideline.
Arrange the letters on the fabric with the adhesive side down, checking for proper alignment and spelling. The letters should be placed face down, with the paper side facing up; otherwise, they will stick to your iron. Use a ruler or a similar tool to ensure the letters are straight and evenly spaced. Once you are happy with the placement, you can secure them with a light touch of the iron to hold them in place.
Before you begin ironing, cover the letters with a protective layer, such as parchment paper or a Teflon sheet. This will prevent the plastic backing from sticking to your iron. Always test your iron's heat settings on a small area of the fabric to avoid scorching. Set your iron to a medium-high setting, typically the 'cotton' setting, and make sure the steam function is deactivated, as steam can prevent a complete seal.
Now, you can start ironing! Firmly press each letter with the iron for around 30 seconds. After ironing each letter, run the iron over all the letters again, paying particular attention to corners and edges to ensure they adhere securely.
After you have finished ironing, allow the fabric to cool down slightly. Then, gently peel off the plastic backing. If the backing resists, reheat the letters with shorter bursts of heat and try again. Be careful not to pull too quickly, as this may lift the letters off the fabric.
Finally, once the plastic backing has been removed, place the cloth back down and iron it again for about 15 seconds to ensure the letters are securely attached.

Apply heat
Applying heat is a crucial step when using iron-on letters with plastic backing to ensure the letters adhere properly to the fabric. Here is a detailed guide on how to apply heat effectively:
Prepare the Fabric and Letters
Before applying heat, it is essential to prepare your fabric and iron-on letters properly. Ensure the fabric is placed on a flat surface to avoid wrinkles that could affect the placement of the letters. Carefully align and position the letters on the fabric, checking that they are straight and in the desired arrangement.
Cover with Protective Layer
Once the letters are in position, cover them with a protective layer. This layer shields the plastic backing from direct contact with the iron, preventing scorching or damage to the plastic. Parchment paper, greaseproof paper, or a Teflon sheet can be used for this purpose.
Preheat the Iron
Set your iron to the appropriate heat setting. The ideal setting depends on the fabric type; cotton fabrics typically require a hot, dry setting. For delicate fabrics, a lower heat setting may be necessary to avoid damage. Always refer to the instructions for your specific iron-on letters and fabric type. Allow the iron to preheat for a sufficient duration, usually around 8 minutes.
Firmly press the heated iron onto the protective layer over the letters. Apply consistent pressure for the recommended duration, which can range from 10 to 30 seconds. Focus on applying both heat and pressure evenly across the letters to ensure proper adhesion.
Cool and Peel
After applying heat, allow the fabric to cool down slightly. Then, carefully peel off the plastic backing. If the backing resists removal, reapply heat in shorter bursts to loosen the adhesive before trying again.
Avoid Common Mistakes
There are several common mistakes to avoid when applying heat. Do not use steam during the process as it can prevent a complete seal and cause the letters to peel off. Additionally, refrain from moving the iron while pressing, as this can lead to uneven adhesion. Finally, ensure you do not peel off the plastic backing too quickly, as this can disrupt the adhesion process.

Remove the plastic backing
To remove the plastic backing from iron-on letters, you must first prepare the fabric and letters for ironing. Wash and dry your fabric, which should ideally be 100% cotton, without using fabric softener. Cut out the individual letters you will be using, ensuring that the margins are even to aid alignment. Place the letters face down on the fabric, checking for proper alignment and spelling. Cover the letters with a protective layer, such as parchment paper or a Teflon sheet, to shield the plastic from direct heat.
Next, preheat your iron to a medium-high setting, typically the ''cotton' setting, for at least 8 minutes. Ensure the steam function is turned off, as steam can prevent a complete seal. Place the fabric on a flat surface, such as a table, to avoid wrinkles that could distort the placement of the letters.
Once the iron is preheated, firmly press it onto the letters for at least 30 seconds. After this, start peeling up the plastic backing. If the plastic resists, apply the iron for shorter bursts of heat. Be careful not to pull too quickly, as this may cause the letters to lift off the fabric. Similarly, avoid applying too much pressure initially to prevent the letters from shifting.
If any letter edges lift, re-iron the area with increased pressure for around 15 seconds. Run the iron over all the letters, focusing on the corners and edges, to ensure they adhere firmly to the fabric.
