Before working your chosen stitch, work a line of double running stitch with lace thread, just inside the outline (see stitch entry ‘Double running stitch’ for further information and method).
Work your chosen stitch along the line, covering the double running stitch. Buttonhole stitch has been used here as an example.
Remove the fabric from the frame. In the middle of the line you wish to remove, use a tapestry needle to hook up just one thread of the fabric and pull it up a little.
Slide the point of one blade of your embroidery scissors under the same thread, beside the needle, and snip the thread. Sharp-pointed curved scissors are most useful for this.
Move along the cut thread, using the needle to tease it free of the fabric. Continue this to the end of the line, and then do the same in the opposite direction.
Once all the necessary threads are unpicked right up to the stitching, life them all up, away from the fabric and slide one blade of your embroidery scissors underneath.
Move the scissors so that the flat of the blade rests against the stitching and carefully snip the threads. By ensuring that the flat of the blade is against the stitching, you reduce the risk of cutting through your stitches.
