I would not use any serger thread for quilting or piecing. It is designed to be used in a close overlock stitch that is fine for garment sewing and project that ravel easily. Serger threads are two ply and linty. Check it for breaking....it is not strong. Wall quilt, maybe. However, with all the work that goes into your quilt, why would you piece or quilt with a lesser quality than your design and construction talents warrant. Best threads for me when sewing or quilting.
When sewing garments, I could not do without my serger and Maxi Loc, but that is what it is designed for.
