I'm currently exploring reliable suppliers for our fabric needs and would like to gather more detailed info about the cotton you use in your products. Specifically, could you provide insights into the type or grade of cotton you source, and any relevant certifications or eco-friendly practices associated with it? Understanding the quality and characteristics of the cotton you utilize will help us assess compatibility with our product requirements. Additionally, if there are specific blends or variations you offer, I'd love to learn more about those options as well. Thanks!
