- 70/10 or 80/12 Microtex/Sharp or Embroidery Needle (80wt in the bobbin)
- #10 hand sewing needle
For hand sewing, use a short length of thread, around 12”-18” to reduce tangling and breaking.
50wt - Orange spool
Aurifil’s 50wt thread is our most versatile and most popular Cotton thread. The 50wt 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.

40wt - Green spool
Because of its slightly thicker weight, it is perfect for use with sewing bags, toys or dolls, garments, or when a more defined topstitching or quilting pattern is desired. It is also terrific for Single, Double or Triple Strand Cross Stitch, Hand Piecing, Bobbin and Machine Lace, Machine Applique, Machine Embroidery, Edge-to-Edge, Pantographs, and Custom Longarm Quilting.

- When using in a Longarm machine, quilt slowly, using a longer stitch and silicone conditioner where necessary.
