Tracing a drawing from a previous Layer.

[handrawn]

why move it when you can create it in situ? - what if you are wanting the head[s] traced on one layer, the limbs on another, the torso[s] on another..... surely easier to be methodical from the off rather than have to sort it all out afterwards?

I have no idea what the OP wants, so it's probably academic

Great points made by all. From this one post, I can see that this is a VERY helpful, engaging group!
