Many years ago when my friend Jude and I did our City and Guilds Machine Embroidery, Jude made a tiny but exquisite sample of feather stitch that looked just like a barnacle encrusted rock. So today in my City and Guilds class when we worked through samples of whip stitch, moss stitch and feather stitch there were several attempts at barnacles. There is something quite satisfying about working very small... these barnacles are only about 0.5 cm in diameter.
Still working small... there have been more buttons. Hand stitched this time and carrying messages.
