What Is Sashiko?
Sashiko, pronounced: 'sash(i)ko' (the 'i' is almost silent),
is a form of quilting originating from Japan centuries ago.
Japanese peasants practiced a running-stitch technique called "little stabs" to patch torn or worn clothing.
As cloth and thread were scarce, it was vital to mend clothing.
The books tell much of the history of sashiko as well as
adapt the traditional Japanese stitchery to modern day stitching techniques.
You can choose to be traditional or very modern in your approach.

Give it a try.  I warn you that it is very addictive!!!!
