Our sateens are supplied by a company we found quite a number of years ago when we were in need of a Portuguese flannel vendor. Luckily, they provide great flannels and we have broadened out what we purchase from them to include our sateens. Just to plug the company, they are Spechler-Vogel Textiles out of New York City.
Sateen has the feel of satin or silk, but in pure 100% cotton. These sateens are combed and mercerized Pima cotton of the highest quality. I wish we could find a broader color selection, but these are what we have been able to procure. In fact, I would like to see the color selection to be broadened out into brighter more wild colors. This is on my wish list.
