OK thanks -- will give it a try

ok you'll have to explain "circle evolvent spiral for a core path" I'm fairly new to inkscape and just tend to do basic stuff. Thanks

Here is a picture I pulled out of a mag. to show what I'd like to do.

I'm trying to put text into a spiral for scrolling and can't quit get It to work. I can move the text onto a spiral but can't get it to close up. I need each circle of the spiral to touch the one above/below. Any thought on how I could do it?
