Advantages and disadvantages of using fabric pens?

Fabric pens offer the advantage of vibrant colors and precision for detailed designs on textiles, making them ideal for crafts, fashion, and personalization. They are generally easy to use and can be permanent or washable, depending on the type. However, a disadvantage is that some fabric pens may fade over time or bleed through thinner materials, potentially ruining the fabric. Additionally, they may require heat setting to ensure durability, which could complicate the application process.
