I also use variegated King Tut on my longarm and usually use a coordinated solid Bottom Line on the back. I have used the variegated on both. If you have a quilt without a busy design, the thread is beautiful. As others have said, it can get lost on a busy design. King Tut and Bottom Line do not cause as much linting as some threads do. They are also a bit pricey, but the Bottom Line lasts much longer as it is not as heavy a thread.
