I play around with the Tracer once in a while, but I'm not sure how useful the "tips" are to other individuals.

But the last couple of things I have been playing around with:
- Creating a black and white trace - and drawing in the detail on the "negative" - with white.

- Creating low-detailed trace with no fills - and stroke shapes on the lines, as a basis to build a sketch (continue sketching) from.

- Massacring imagery in Photoshop before tracing, in an attempt to create imagery I could use for silly comic strip-like imagery. Xara Tracer comes up with pretty neat shapes when tracing, small-sized images, with little detail - such as a the result from the "find outlines" filter in Photoshop etc.

I have been playing around with all kinds of little things... but I don't save it, unless I find a potential use for it. So I end up putting it in the back of my mind, until the next time I play around with it.

Nice to see you again, Tad! And thanks for sharing!
