Susan's comment - 'Although this is the slightly finer of the two Olympus kogin fabrics, I find it is easier to stitch because the holes are slightly larger and the threads finer than the 18 count evenweave cotton fabric. It has a more "handmade" look than the 18 count.  Suitable for our kogin thread, or DMC or Anchor Soft Cotton. My favourite kogin fabric, and the new colours were introduced on my request!'

Translated from Japanese packaging -
 
Notes on linen cloth. 100% linen fabric that takes advantage of the natural texture. Linen fabric produces black and brown knots and slubs.  Please note that you may break the thread if you try to stitch too forcefully. There may be a slight error in the thread count number due to unevenness in the weave and thread. Please understand that this is a perculiarity of linen fabric including a feeling of wrinkles and distortion. if the cloth is slightly distorted, please pull the cloth square before starting to stitch.  Please be aware that the cloth ends unravel easily*.
 
Susan's tip - * zigzag or oversew the edges of the fabric before starting to stitch, to prevent fraying.
