Swampy,
I've been practising cloning - using the vanishing point tool - & I see why you like it! Isn't it nice to be able to see where you are picking up from....
My one wish with this filter is that when I make a bad mistake, I would like to go back a step, or erase, and there doesn't seem any option for this (probably because it's a filter.) I wondered how you get round it? With complex cloning I guess you save what you have done already in the filter, leave it, then fix your mistake in the main Photoshop screen, then go back into the filter to continue? Or is there an easier option?
Bart,
Many thanks for those suggestions. I am still knee deep in the Vanishing Point Filter (quite a lot to learn), but the next thing on my list will be to follow up your suggestions. In the next week or so I will come back to let you know how I get on. Using a variety of pattern variations sounds a good way of tackling the problem of a very small sourcing area.
