This is not a favorite stitch of mine. I did do two on my block, in a very slender perle #12, but it still seemed so heavy and not at all the airy fairy look I wanted, so I broke my cardinal rule and took them out. I should have photographed them first, but I didn't. They come off quite easily, though!
Instead, I did this:
This I quite like and the arches on top are from a book someone on here forced me to buy. The Stitches of Creative Embroidery by Jacqueline Enthoven. It's a combination of two feather stitches shown on page 107. The little blue one at the bottom is badly done, and tempting me to break that rule again. It's from a sketch on the top of page 128. I like the stitch, but I didn't get it very even. I'll see if I have time to take it out later, or if I just mask it somehow. It looks worse in the picture than it is, but it's bad enough.
