I am not a long arm quilter , but often send varigated thread to my L/A pro for use on my tops. I love it. They do use a different bobbin thread a solid. A a general rule for me ..when in doubt as to thread color use varigated! Love the Superior thread King tut varigated.
How it will look depends so much on the thread you pick. I have some varigated that the colors changes are very subtle, and others that have very noticble changes.
