I put this together today using Affinity Photo (my photo-editor of choice). Wanted to see where we have visited Australia (from New Zealand), over many years. It took 70 layers. Some of these layers were partial maps of different parts in Australia, which I used at about 50% opacity to match up exactly where the various place are. I found that some maps are not in the correct proportions so had to use the Move Tool a lot to get them to match the Background Layers. Hugely time-consuming plus I had to work out how to get dotted lines, which I had not done before. As you will be aware, of these 70 layers, most are the place dots and the associated names. I will put into groups these shortly as they take up a lot of space visually.
