This Aurifil 50 wt thread is strong and thin, and results in remarkably flat and crisp seams. While it is wonderful for piecing, subtle quilting, topstitching, and English paper piecing, it also works incredibly well for Needle Turn Applique, Bobbin and Machine Lace, Machine Applique (Straight Stitch, ZigZag, Blind Hem and Blanket Stitch,) Machine Embroidery, Dense Machine Quilting, Subtle Machine and Longarm Quilting, Basting, Whole Cloth and Micro Quilting, and Dense Background Designs.
