Short answer: Original is easier to apply, looks brighter, and can be applied to more fabric types,
Long answer: Our Original formula can be applied to cotton, polyester, blends, and more! It applies easily at a low temperature of 300-320˚, and feels super soft.
The Classic formula will only apply to 100% cotton and 50/50 fabrics. Classic applies at a hotter temperature of 350˚, so it cannot be applied to Polyester fabrics. Because of this higher temperature, the colors may not appear as vibrant.
