Aurifil’s 50wt thread is Aurifil's most versatile and most popular cotton thread. 1,422 yards of thread are wound on Aurifil's iconic orange spool. The 50wt thread is strong and thin, and results in remarkably flat and crisp seams.

While it's 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, Zig Zag, 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. 80/12 Microtex/Sharp or  Universal needles are recommended.
