I was thinking of tackling a larger piece made with some of those and slightly smaller ones (as shown in the book) but after tatting this one, I'm not so sure.
It feels a little crowded around the tips and there's a bit of tension in places and I'm not completely happy with it. I also think it would be one of those designs where I'd need to constantly refer to the diagram...
Oh well. I think I'll try something else.
