Our buckwheat pillows are made with an organic, custom woven fabric developed just for our pillows. Organic cotton is what our fabric is made from and twill is how the fabric threads are woven together.
Think about weaving - a weft thread will go under, over, under, over a warp thread. Twill fabric is made by changing the pattern so the weft thread will go over more than one warp thread before going back under. There is also a step between weft threads. This creates a diagonal pattern in the fabric.
Denim is a good example of twill fabric. If you're wearing jeans, take a look and see if you can see the diagonal pattern in them. Like a good pair of jeans, the twill we use to make our pillows is durable for many years of use. Unlike jeans, our fabric is undyed natural cotton.
