The irregular shapes of some of the circles make the embroidery rather challenging - I have to decide whether to treat the shape as essentially a circle, or whether to embroider in line with the white areas.
Mostly, I have tried to keep a circular design. I'm not sure that this large double circle above has come out very well. Perhaps I'll come back to this later if I get some inspiration.
This smaller circle works better, although it has irregular features. I can't find my box of embroidery cottons, so today I bought 20 more so I can get some more colours onto this. Hopefully, the silks should arrive soon.
