This pattern, when viewed horizontally, has the appearance of a capital ‘T’ or a bricked pattern with a diagonal line running through the centre.
It is a very detailed pattern and works well in more linear formats.
Stitch a cluster of three parallel stitches each over two threads and one thread apart.
Continue to fill the area to be stitched with identical clusters, each cluster six threads apart
Work over the space again filling in the spaces with a large horizontal and a diagonal over six threads. Working across the area diagonally will avoid dark threads trailing across the back of white fabric.
