I have used MaxiLock too, and it does fine. I've even used it double stranded.
It is a lighter weight than "quilting thread," so take that into consideration when you think how the quilt is going to be used.
But as far as what kind of threads can be used in quilting a quilt, art quilters and thread painters go really wild sometimes in their threads and filaments, and it comes out gah-juss!!
