Make font THICKER

[masque]

OK sorry.
Same solution.
Bold text add outline and make it the same colour as fill to produce thicker letters
Duplicate and turn outline black on duplicate and make thicker still and place behind. Adjust outline of front object to make letters thicker or thinner as required.
Adjust outline of back object to give you the thickness of outline you want.

You can use the contour tool and then "inset path".
You don't even need to convert text to shapes, it works straight from any text.
