In trying to add a  1cm seam allowance outside a pattern drawn with Inkscape 4.8, :
1. the Outset is shaped properly, has the correct width, but it is positioned *over* the path, half in and half out, instead of being placed 100% outside of the path.  Is this the intended behavior?
2. The outset doesn't inherit the properties of the path selected, it has a 'fill' by default. I have to select the edit object icon, and set fill to 'x' and stroke to solid.  Is there a way to cause the 'Outset' path to inherit the selected path's properties?
3. When I select 'Inset' on the same path,just as a test to see what happens, I get a very small tight grouping of points that have no apparent relationship to my pattern shape. I don't really need 'Inset' at the moment, just thought I'd mention it.

I'm new to Inkscape, so perhaps there is something that I am missing.

Any suggestions?

Thanks, 
Susan
