Being currently rather taken up with circles and allied things, I went browsing more deeply on Donna Watson's lovely blog.
I came across the following definition of a circle, taken from Japanese elements of design:
MARU: Circle. Extending a point into a line begins a journey that ends only when the line comes 'full circle' to return to its starting point. The circle thus symbolizes completion. A circle is harmonious and tranquil, yet it represents the cycle that is life. The circle is an opening, a window on the whole of being that it also represents, the eye that sees itself.
On the linked page given above are lots more links to other posts on her blog that I look forward to exploring when I have the time.
And here is my latest offering on the subject of the circle - or in this case, its close cousin, the oval - some eyes that see themselves?
I suspect all this playing will end soon and then I'll have to work out how to link it all to my textile work..... It's certainly been a great time for experimenting and putting together lots of techniques, many of them already known but not before inter-related.
