not really, its hard to find nice indigo fabric.
the stuff i'm using is japanese indigos that i've collected over the last 3 years.
i haven't seen any sites that have it for a reasonable price.
equilter and shiboridragon both have some but its about $9 a yard.
i did buy some kona cotton indigo solid for the triangles and the color is a perfect match to the japanese indigo.
