What's this? 3 posts in one day? Looks like if I will do illustrations flexible for clothing I need to work in vector. Of all the apps that let you doodle in vector looks like Adobe ideas is the best. They fixed the lag from the earlier version, but when I export directly to photoshop on my iPad it rasterizer badly, so adobe still have work to do on the iPad version of photoshop, but Ideas coming along, and it's practical. This image was quite easy and quick to do.
As for the idea itself, if I was a cat and I saw a cow, I would be more frightened than from a dog.
