Azumino-momen fabrics are piece-dyed in the Azumino district of Japan (momen means cotton) hence the name Azumino-momen. Before the pieces are dyed, the fabrics go through a process which creates a natural textured finish that gives the fabric a distinctive feel even after washing. This fabric is a little heavier that regular quilting weight cotton. More the weight of the cotton-linen fabrics. Beautiful for sashiko!
