Haven''t put too much thought into this, but I really don''t think it''s possible. I''ve spent 5 minutes doing this, and I can''t find any way whatsoever.

When you draw your first line, and then your second, that leaves a third, unused line in that corner - where the drawing must end. However, when you arrive the next corner, the same thing occurs, leaving one unused line. ~ You can''t have 2 ending positions.

no, it is impossible.
you can only draw something without lifting the pen when two or less nodes (corners in your case) have an odd number of paths leading to/from it. if there are two odd-numbered nodes, they will be the starting and ending point.
i have no idea why i know this (i must have learned it in some math class or something, years ago).
