My husband purchased a Lil Gracie for me a couple of years ago. We have moved it a couple of times to different area and always have taken the legs off. Mine it set to be able to go from crib to kings size. Unfortunately I have never used it.
I have a standard machine and tried it once but not coordinated enough to get the movement down. Maybe if I purchased a regulator I would actually use it for more than a table to set my machine and cutting mat on. I truly would love to learn how to use it and quilt larger projects. Anyway back to your question. my husband says to definitely take off the legs. Hope this helps
