Linen bed sheets are less explored, which explains why there are fewer types of linen bedding on the market. The highest quality linen lies along the world-renowned Western Europe flax belt - crossing through Belgium, France, and the Netherlands. The climate along this belt is optimal for growing and harvesting flax, bringing about the Belgium and French Linen we hear of today.
However, flannel sheets can be made of cotton, wool, or synthetic fibers, leaving brushed cotton a good balance of breathable and warm.
