The Algerian Stitch is a kind of Cross Stitch somewhat akin to Cretan stitch, but worked on canvas. The stitch may either be worked very closely or openly.
Bring the needle to the right side of the work. Count about five threads down, take up three threads. Cross over to the top line, and continue in the same way.
This stitch can also be done as a double stitch and is named, appropriately, Double Algerian Stitch.
To achieve the Double Algerian Stitch, work one row of Algerian stitch, and then another row between the first in a different color. The illustration below shows the dark lines representing one color and the lighter lines another.
