Stitch Library by Technique
Hand embroidery stitches grouped by the stitch family
There is no one official or right way to classify the stitches.
On this page – Stitch Library by Technique, you will find hand embroidery stitches categorized by the technique used to embroider, also called stitch families.
I think that hand embroidery stitches can be grouped by the technique used to make them or by their purpose in surface embroidery. I wrote an article “Hand embroidery stitches, stitch groups, and families. The classification of hand embroidery stitches by purpose and technique” on this matter.
If you are looking for a specific stitch by its name, check out the Stitch library A-Z page.
