Square boss stitch
- Raised knot
- Square boss

This is a cross stitch with a diagonal stitch over each of its corners which join to form a raised square. The stitch is normally used as an isolated stitch, although it can be worked in rows to form a border, or as a filling stitch either evenly spaced or randomly scattered.
Rice stitch (canvaswork) is a similar stitch which is used as a canvaswork filling stitch.
Method
First, work a cross stitch.
Then work a back stitch over the bottom right arm of the cross stitch.
Next, cover the bottom left arm of the cross stitch with a back stitch - your stitch should end where the previous back stitch started.
Work another back stitch, this time to cover the top left arm of the cross stitch, again sharing a hole with the previous stitch.
Finally, cover the top right arm of the cross stitch with a back stitch - this stitch should complete the square.
