Isn't this a lovely stitch? I found it in one of my new books, "Three Dimensional Embroidery Stitches". It's the raised chain band and is very easy to do. I was lucky that my fabric was printed with squares so it ended up quite neat. I used Sassa Lynne #5 because it changes colour quickly.
This is a snowdrop and I tried the woven leaves. I found using a long needle instead of a shorter pin worked much better at holding the picot in place. The stem in the book was Palestrina stitch, but I had forgotten how to do it and couldn't quite understand the instructions. I did stem stitch and wove another thread through it.
