The 'V' is outlined in three strands of dark purple thread, and has been filled in with satin stitch using 6 strands of thread.
The blackwork patterns nearest to the 'V' have been stitched in one strand of thread, and the patterns nearer the edge of the hoop in 2 strands of thread. This was to give the hoop a more textured feel.
Hoop is wrapped in purple ribbon.
The blackwork pattens were all taken from the Royal School of Needlework's book on blackwork, by Becky Hogg.
