Premium Cotton Twin Bed Sheets

I'm in need of skilled manufacturers to create top-notch stonewashed cotton bed sheets for single and double sized beds. Bed sheets will have a key difference where they have a zip connecting them together, unlike anything currently on the market. Applicants should have experience in textile manufacturing, specifically with the production of cotton bedding items. Knowledge in thread count specifications and bed sizing is a must. Expected deliverable is high-quality, durable, and comfortable bed sheets made of 400-500 thread count cotton.
