​Usually worked on an even-weave fabric to ensure equal length stitches, a row of running stitches is worked, then another row of running stitches is worked in between the first row, sharing the same holes in the fabric to create a continuous line.

Double running stitch has been used for centuries: it was found on a medieval fragment which was excavated in Egypt.

The name Spanish stitch dates from at least the 16th century when it was a popular blackwork stitch.  The name ‘Holbein stitch’ is credited as stemming from Hans Holbein the Younger, the 16th century portrait painter who showed blackwork cuffs on his subjects.  It was also popular in redwork embroidery across north-western Europe and further south in Lagartera, Spain and Assisi, Italy.

The use of Double running stitch extends to Morocco (both Fes style and Meknes) and to Syria where it is used on garments in Qalamoun style embroidery.
