Twill fabric is handwoven with handspun cotton growing in Magwe region in Myanmar. Spinning and weaving are mecanical processes only done by hand. Colors come from natural dyes. Dark brown is dyed with gooseberries, called "mon dhi". Beige comes from "nabu" which is a bark of a tree. Well known indigo plant gives the blue. Ecru is natural cotton color. Cotton seeds are brushed out of the yarn manually. However, some of them remain in the fabric and are visible.
Mon dhi and Nabu versions are half dyed, half natural ecru. Indigo version is plain blue.
