Always check the fabric care label of your garment.  Leather, plastic, and waterproof materials cannot be ironed.  In this case, please use fabric glue or sew on your Joy letters and numbers.

You can use fabric markers, fabric dye (liquid or powder) or fabric paint.  Please follow the manufacturer's instructions.

Wash inside out in cold water and air dry.  Joy letters may be dry-cleaned.

The key to creating a permanent bond is in the application, meaning a combination of heat, pressure, and time. Using a home iron, check that your setting is in the correct position. Typically, the settings are shown either as degrees, or type of fabric. Use the highest heat setting that your fabric will allow.  Next, 30 seconds ironing the front and then 30 more seconds ironing on the back works best. Last, the amount of pressure used is important.  Firmly press your iron onto the letters and ensure it is rotated to completely cover all of the letter(s). If ironing on a name or word with multiple letters, iron one section at a time.

Usually, the fabric content will be shown. The more natural the fiber content is, such as cotton or wool, the more heat can be safely applied. Man-made fiber content such as polyester requires that you reduce heat. To compensate for less heat, add more time and pressure.

Yes, these are sticky back letters and the paper liner protects the adhesive until letters are applied. Peel away the paper liner, and place the letter in position. This allows you to check the position and get it perfectly aligned. If not, just peel the letter off, and reapply until you’re satisfied with the positioning.

There are times, although rare, where after the letters are laser cut from the base fabric, the heat seal remigrates back to the base fabric and the letter “sticks” to the fabric. Using a small sewing scissor or X-Acto knife, carefully cut around the outline of the letter, avoiding cutting into the threads.

Reheat the iron to the same settings as when letters were first ironed on. Have a pair of tweezers handy.
Cover the letter with a pressing cloth, using firm pressure, and iron for 30 seconds.  Immediately remove the pressing cloth, grab an edge of the letter with the tweezers, and peel the letter off.

Caution: The letter is hot to the touch.

In most cases, there will be sufficient adhesive to reuse the letter. However, any leftover residue on the garment can be removed while still hot, using a blotting paper or small piece of cloth.
