Here is what I learned in the year and a half since purchasing my longarm.
You must have adequate space for it. It takes over an entire room.
I love the free motion of it, but a stitch regulator is a must.
I purchased mine on ebay (shock!) from a dealer. It was a trade-in on a larger model. Don’t overlook used models.
I have learned from MANY sources on the web and utube the how-toos. They are invaluable resources!
I finished many UFO quilts and am in love with my longarm.
I have a Gammel Superior ultra, with a 12’ table. It had 40 hours of use when I purchased it.
I have free motion quilted 25 quilts since ownership.
My husband convinced me to take the plunge and is now building me a dedicated quilting room.
Good luck!
