Fly stitch filling
- Crossed fly stitch

This surface stitch uses joined rows of fly stitches to form a trellis of diamond shapes.
It is similar to cloud filling stitch, but its different structure normally gives a more angular effect.
Method
Bring the needle up through the fabric and back down short distance apart - this will be the width of your diamonds.
Leaving a loop on the surface, bring the needle up again centrally below the two points to form a triangle.
Draw the excess thread to the underside tightening against the needle to create a V shape.
Draw the thread to the surface and use a small holding stitch over the thread to secure.
Repeat to complete a line of fly stitches; each stitch should start by sharing a hole with the previous stitch.
The line below should be worked as a mirror image; the holding stitch is positioned over the one from the previous row.
Continue to cover the area to produce a diamond trellis.
