Sanded it all back and mixed up a different blue. Stained the whole thing purplish blue first. Wiped over the centre to lighten it. Then added a bit of magentaish purple to the centre. And finally a bit more blue around the edge.
I'm liking this one much more. But it turns out the wood on the edges is much more yellow coloured so the blue isn't quite a nice as in the centre. Hope it looks OK when it dries, and with a clear coat on it.
