For sewing thick materials, a durable machine is non-negotiable. Look for machines with a solid metal frame rather than plastic components. A heavy-duty sewing machine will not only provide better stability but also withstand the rigors of sewing multiple layers of thick fabrics.
4. Needle Compatibility Heavy-duty projects often require specialized needles, like those designed for denim or leather. Make sure the machine you choose is compatible with a range of needle types, ensuring you can tackle various materials without hassle.
