I've discovered the magic wand tool this week and played about with it . This is an image of a rusty tractor wheel similar to the one in the last entry. These are some of my favourite colours (even though I try to get away from them!) - I'm still working on a way to be able to combine images like this using a transparent background. I expect it's quite easy but it takes me ages to work it out by trial and error but it's fun getting there! As usual, the handbook doesn't go into so much detail ..
