Including my poor sewing machine. I stumbled onto this really cute mom-son pair cleaning up their sewing machine, and realized I really need to do the same (minus the adorable son). I've been using mine for about 7 months now and have never really cleaned or oiled it. It's a pretty cheap machine but its still a big no-no if I want it to last any amount of time. And not angrily eat the fabric I'm trying to sew.
Better get to cleanin'!
