Making Pretty Buttonholes
5. Cut the buttonhole open with a block and chisel. Place the chisel on the buttonhole and cut the opening by working from the outside edge toward the center at both ends.
6. Check the buttonholes for any loose threads. With small sharp embroidery scissors, snip any loose threads along the inner section of the buttonhole.
I will also 'clean finish' ready-to- wear garments. I check the buttonholes, ends of seams for loose threads and trim them off. It increases the price of a garment, whether one of your designs, or purchased.
