Diamond Eyelet (single)
This is a pulled thread stitch, where sixteen stitches radiate out from a central hole to form a diamond shape and are pulled tight to create a central opening.
For more information about eyelets generally, see the entry for Small eyelet.
Method
Bring the needle up and make a horizontal stitch four threads to the left (this is the position of the centre hole).
Bring the needle up one thread below and one thread to the right of the the starting point and pull.
Take the needle down in the centre hole (three stitches to the right and one stitch up).
Follow the diagram for the placement of the stitches, and continue round the eyelet.
Pull the final stitch.
The finished eyelet.
