A hat hoop is strongly recommended for embroidering hats, especially if you want a good outcome. Without the use of such a feature, you’ll find it a more challenging task to work on. When using a hat hoop, you need to ensure that you place it in securely, so it remains straight and centered throughout. Without the aid of a hoop, this is increasingly difficult to maintain. If you’re going to be embroidering hats on a regular basis, this is one feature worth having to hand, whether it comes with the machine itself or is purchased separately.
