I sliced this plum heather Gap top right up the centre through the cowl neckline then put a narrow lettuce edging on the cut ends with a mix of purple and grey thread. Each cut edge had three rows of zig zag stitches at the same width but different lengths. I also alternated the sides of the fabric so that the outer edge had some purple and some grey.
Couple options for wearing: pin it closed and pull the neckline over the shoulders or just leave it open and all drapey.
(And read some of TWD Compendium 3 which was delivered bright and early today!).
