美国采购需求：双面针织面料、双面针织面料、双面针织面料、涤棉面料、涤棉面料

I run a doll clothes business and I'm really interested in sourcing some fabric for my projects. Specifically, I'd like to order 8 yards of your interlock knitted fabric that consists of 40% cotton and 60% polyester, in both black and white colors. Quality is super important to me, so I'm hoping to receive a swatch of these two heavy interlock fabrics. If sending out a swatch is possible, please let me know. I can provide you with my mailing address as soon as we confirm this. Looking forward to your prompt response!
