ImageLines with styles

Hello.  I'm drawing line graphs and for each line they want a different
style (dots, dashes, etc.).  I can't find a way to make the line draw
thicker than normal, and the regular thickness isn't thick enough.  I've
tried drawing 3 lines next to each other, which works fine with solid lines,
but it looks pretty bad with the styles on because the ends don't all end in
the same place.  
 
Does anybody know of a better way to draw thicker lines?
 
Thanks!
