Victorian step stitch
This is a diagonal stepped stitch worked in vertical stitches on an even weave canvas which resembles the treads of a staircase in profile. It is made up of a long vertical stitch, followed by three short ones - the long stitch forms the riser of the step and the short ones the tread.
Method
Begin with a vertical stitch across four canvas threads.
To the bottom right of this stitch make three vertical stitches across two canvas threads (the bottom of all four stitches should be level).
In line with the top of these stitches, begin another long stitch over four canvas threads which should end two canvas threads below the last stitches.
Continue stepping the stitches, making three smaller stitches then one long one.
The second row should fit into the gaps of the first, with the first long stitch of the next row sitting to the left of the leftmost long stitch of the previous row. The top of the long stitch should be level with the previous rows of short stitches.
