Be aware, if you quilt for others and are paid for it, your longarm is considered a business item and will not be covered by your homeowner's insurance.
If you pursue this, you will also be well-advised to get business as well as liability insurance. If someone were to trip and fall bringing or picking up a quilt, again, your homeowner's won't cover you for their injuries or if they filed a lawsuit.
Very worthwhile points to consider.
I said "good points" at first, but they are more in the "Oh, *#$%" category.
