This is/was/will be round 4 eventually!!!! I got to the end of round four (middle picture) and realised there was a mistake in round 3!!!
Well that's a whole round cut out!!!
Guess what? It was totally and utterly my own STUPID fault too. Can you see that in round 3 there is a join to the middle of the two joined picots - where the cut threads are? Well, I missed one join there. I'd checked before starting round four too and it all looked fine. The bottom picture is the sad remains!!!
When I had cut it off and started wondering quite how to repair round 3 I found that it was actually the last part of that round where I'd gone wrong so I was soon on my way again. More another day!!
