Sashiko versus kogin: what is the difference?
Kogin belongs to the wider family of Japanese stitched textile traditions often discussed alongside sashiko, but it has a distinctive counted structure, cloth and thread weight.

Sashiko follows a marked or planned line
Many sashiko projects use running stitches along drawn, printed or mentally planned lines. The design may be geometric, pictorial or used directly across a patch. Stitch length and spacing create the visual rhythm.
A stable cotton cloth and purpose-made sashiko thread are common choices, although the exact materials vary with the project. The technique can be decorative, practical or both.
Kogin is counted across an open weave
Kogin patterns are formed by counting the fabric threads, usually working horizontal rows across an even, open weave. The stitches build dense geometric motifs from the structure of the cloth rather than following a line printed on its surface.
Purpose-made kogin thread is thicker than fine sashiko thread, giving the counted design a substantial appearance. Kogin cloth exposes a regular grid that makes the counting possible.
Which should a beginner choose?
Choose a printed sashiko sampler if you want to practise a relaxed running stitch without counting every fabric thread. Choose kogin if you enjoy charts, repetition and counted embroidery. Neither is inherently better; they reward different kinds of attention.
Do not swap the materials blindly. Thick kogin thread may crowd a closely woven sashiko cloth, while a fine thread may look weak on open kogin fabric. Match the thread, needle and weave to the intended method.
