The pattern I've replaced it with and which looks a bit like leaves is from the "Cap shawl" (also in Victorian Lace Today) and I think it works well with the border above it. Now those circles almost resemble flowers, don't they? And the lines above them could be rays of sunshine or perhaps rain. (Provided the wind blows from opposite directions simultaneously!)
The yarn looks grey in this photo, but it is jet-black. I like the colour: even if I could see the shawl in any colour, this choice makes it both dramatic and elegant. It could be interesting knitting the same combination of patterns with different colours, for example green stems & leaves, red flower circles and blue sky. On the other hand, that might make the idea very obvious, not leaving much to imagination - and I like it when things aren't too obvious. Besides, I do prefer lace knitting to be one-coloured to do justice to the patterns.
