Round eyelet (pulled thread)
This is a pulled thread stitch, where multiple stitches radiate out from a central hole to form a circle and are pulled tight to create a central opening. Each stitch is brought up in a different hole in the fabric and goes down into the central hole of the eyelet. They can be worked individually or combined with other pulled work stitches to form a filling pattern.
Bring the needle up and make a horizontal stitch four threads to the left (this is the position of the centre hole).
Follow the diagram for the placement of the stitches, and continue round the eyelet.
Pull the thread each time you bring the needle up through the fabric, to maintain a neat hole.
