Thank you so much. Since posting I had another think and look at it and I decided to go ahead with how I was doing it. It really doesn't look that bad...lol. I also realised afterwards that I needed to use colour in one part to define part of the quilt anyway and it would have looked funny if some was invisible and some wasn't. Yes, I think I was being a bit over fussy...as we often are with our own work..lol.
