希腊采购需求：珠纱，羊绒纱，花式纱，功能性纱，手编纱，针织纱

I'm looking for more detailed information regarding your knitting yarns. Specifically, I'd like to know the different types, materials, colors, and weights you offer. Additionally, it would be great if you could share any available customization options and minimum order quantities. Could you also provide the pricing structure and lead times for both bulk orders and samples? If you have a catalog or product sheet, that would be super helpful for us to evaluate and make decisions quickly. Thanks in advance for your assistance!
