I have my "in use" machines set up in a row. I can slide the Emb machine down if I need more room for things like sewing on bindings at the Juki (straight stitch machine).
I also have an older pfaff emb machine sitting on an even older Singer cabinet past the serge - so I can use that if I need a swing needle machine while the Babylock emb machine is in use.
My LA is out in it's own shed, no room for it in the house.
