Encouraged by the response to circle no. 1, I have made circles no.2 and 3. I tried swapping the segments round this time, so one quarter of each doesn't belong with its fellows. I'm not sure I'd bother doing it again: I don't mind it, but don't like it any better than the original version. Having said which it's nice to have a bit of variety. I've stuck them up on the wall with the 9 patches and, for me, now, this starts to look like something.
Looking at this post I've just realised: one more and I can make a big 9 patch out of my little ones. That's an idea that pleases me.
