She just wanted the piece of fabric made into a rectangle and sewn up the sides... but could I really just give her back a plain black scarf, unadorned?? Of course not. This was perfect for some black lace which I think looks really elegant.
Here it is:
I used a few repeats of the lace for a collar pattern in Jan Stawasz's second book, "Tatted Treasures", the one one page 74. I was looking for something reasonably wide and this fit the bit perfectly.
If I was doing it again, I would probably omit the little flower down the side of the lace but I decided it didn't bother me enough to start over again. I'm happy with the rest of the lace.
