Aurifil 12wt thread is the master of all heavyweight threads that will feed through a sewing machine. Although it is regularly used for hand embroidery and wool appliqué…

Aurifil 12wt.

it is an absolute favorite for Topstitching use.

Sheen, definition, consistency — everything about using this weight for topstitching is a WIN! The thread just looks fabulous. Isn’t it beautiful when used for a double line of topstitching!? Quilt shown is A Wing and A Prayer, prepared by Jan Manley. See more 12wt topstitching here: Karen’s Quilts, Crows and Cardinals: Summer Vacation – A Wing and a Prayer (

Aurifil 12 WT


  • Play with Aurifil 40wt or 50wt in the bobbin. My style requires me to use 40wt, but your speed, tension and stitch length may allow you to use 50wt.   NOTE:  50wt is more cost effective, so if your machine likes it, go for it!!    
  • Choose a topstitch needle size 90/14 or 100/16. Increase the stitch length and consider dropping your top tension to a slightly lower number.
