Would it be possible to store a machine where you take your classes?
I have a rolling case for my sewing machine and stack my project bag on top... to take from my apartment to my car to my quilting group. Then I only have to lift to put into my car or the one step from the porch to the sidewalk... which I find manageable. But I'm not above asking for assistance either. I just like to do as much as I possibly can - even with a bad back.
