One Day Project Turning into Week

  These projects are supposed to be one day projects.  I don't believe the author intended an entire day spent on the project, as most people could not spend that much time everyday for a year on projects unless it was of course their occupation.  Well, the shoe project has definitely taken more than a single day, partly due to my screw up.  I included pictures of my first attempt at decorating the $3 Wal-Mart shoes which resulted in a mawkish design.  The next project is not officially finished.  I spray painted the shoes with a single coat, then taped a design and sprayed them with another color.  It didn't turn out.  So, I sprayed them over again with the origninal color.  They are better but not great.  I still have embellishements to sew on by hand, however, I feel as if I am falling behind.  Do I continue to work on the same project that was only supposed to take one day?  Am I spending too much time?  Should I move on and try something else?  I don't like leaving these unfinished.  I was going to try to start something else while the shoes are drying.   (I actually made a black apron for work while I was waiting before.)  I know I won't leave them unfinished, I just don't think I can but should I continue to let these projects take up more than one day?
