Thanks for the tip. Finding that little control node is always a challenge in this function. Especially helpful for getting an easy outline shape around a group of text.
One issue that comes up with the way Inkscape does offsets is that it doesn’t replicate exactly the contour of the original shape. You can do some tweaking with preferences, but in the end it doesn’t work very well for doing inlays and kerf offset for very small features.
Here is a good topic that puts this technic to use.
And here is a much longer and detailed topic that does a long exploration of techniques to get good offset finally be using path widths and converting stroke to paths.
