An Inkscape user mentioned trying to follow this Illustrator-based tutorial on outlined lettering, but said he was having some problems. To get the user going, I pointed out Troy Sobotka's tutorial on text styling. It gets a bit more complicated, but does present several nice features that got the user going even better.
However... I thought that the basic techniques used by Illustrator should work fine with Inkscape, so I pulled things up to take a pass at following it. It turns out I was right, and it wasn't hard at all. In fact, it turns out to be doable with fewer steps. So here is a basic summary of the changes in approach needed to achieve the copy-n-past over text effects explained there.
Start by reading the tutorial on "Lettering: Multiple Outline SFX". It seems pretty straightforward, right? Since adding a thick stroke often doesn't work the way one might want it to, I was quite familiar with the approach of pasting a copy over a thickened version.
2. Group them, apply a stroke, and set the desired thickness. Depending on the size of your text, you'll need different thicknesses. (If you look closely, especially at the hole in the 'A', you can see how this version is thicker than the original)
3. Duplicate the text and set the fill white and turn off the stroke. This is the part where it varies a bit from Illustrator. In Inkscape, all you need to do is "Duplicate" the grouped paths/object using Ctrl-D (That will combine the separate copy and then paste-in-front that were called for in the Illustrator tutorial).
Moving on, one can also follow the other techniques there. Using the simpler 'duplicate' saves a tiny bit of time, but the general principals are solid and the skills transfer easily from Illustrator to Inkscape once the specific keystrokes are not hunted for.
