Why order a swatch:

We hold up each fabric in natural sunlight, twist it, turn it, and then photograph it and describe it with the eloquence of a Shakespearean writer. Regardless, words and images pale in comparison to holding a sample in your hand to ensure it will work for you.

Plus our lawyers say: Variations in monitor or mobile color settings are vary widely from device to device. Therefore we strongly encourage you to order a swatch before purchasing.
