Spaced cross stitch filling
This filling stitch consists of diagonally offset cross stitches spaced across an area. The stitches can be widely spaced, or stitched so that the corners touch. It can be worked on either evenweave or plain weave fabric.
Make a diagonal stitch lying bottom left to top right over three intersections.
Bring your needle up at the top left and take it down at the bottom right to complete your first cross.
Count your desired number of threads to the right and work the next cross stitch in the row.
To work your next row, bring your thread up at the top right corner of the cross and take it down at the bottom left corner. Work the top stitch from bottom right to top left and continue.
