To begin, a row of interlocking squares is worked. Make a tent stitch across one intersection of the canvas, then below it make successive stitches across two, three, two then one intersection again.
Repeat these stitches to produce a diagonal pattern of interlocking squares across the area being worked.
Adjacent to the squares, work a row of tent stitches following the step of the squares. These should be three tent stitches up and three tent stitches across.
Next, work back down the other side of the tent stitches, fitting the square pattern into the spaces left by the tent stitch.
Structure of stitch
This stitch is worked in diagonal rows and is very similar to Scotch stitch.
This slightly more textured version of Scotch stitch. It is good for backgrounds and filling areas quite quickly. The pattern gives a nice diagonal stripe.
