I've been like that too, lately. I have a table topper that I'm making for my daughter. All that is left to do is finish the FMQ, which is about half done, and the binding. I've been putting it off and don't know why. Part of me wants to start something new. So part of my procrastination has been perpetuated by purchasing more fabric for other projects, designing a new pattern for a soon-to-be born new grandson, etc. etc.
I guess when you figure out the why, if you share the reason, it might help me understand my own delay in finishing!
