Today I realized a couple of things. First, just because you can UN-screw something, doesn't mean you should. I was going to clean up my treadle and started by shining up some gunky spots and decided to undo the stitch length do-dad. Um, that little part INSIDE the machine is really hard to reach and this brings me to the second thing I learned. Sewing machines get really DIRTY inside. So, it's back together again, but I am re-thinking my idea to just clean it from the outside. Maybe I really should soak it in de-gunker after all....
OK, I learned something else. I can't wait to piece a quilt with it. I really do love treadling that machine...but maybe I'll make sure it's clean first.
