Wow, great idea. What I really don't like about mine is that it is difficult to lift into the trunk of my car...you know...up and over then down. After using it a couple of times to go to quilt classes, I just gave up and went back to using the hard carry case that slips over my viking. It slides perfectly onto the floor in back of the driver's seat. And since this is the only place I ever take my machine, it is not a problem. There is parking right outside the door so I never have to carry it far. I think any wheeled transportation device is a good idea when one has a distance to go. Your idea just proves that quilters are really creative thinkers! :)
