I spent some time recently just blog hopping, and there I found what I needed. I hadn't been on a search per se but when I spotted 'blogging tips' at the top of Sarah's blog, I knew this was one to share.
There are lots of images and clear instructions from Sarah at Faded Country. I do my images in PSE but the ideas of how to do it are clear enough for any photo editing program you use. Check out her blog too for a lot of very easy to do decorating projects, all in the Faded Country Style. Thanks Sarah!
