Description
WonderFil Accent™ is a 12-weight, 2-ply rayon thread with a high sheen, made for decorative stitching that stands out. This listing is for one 400 m (437 yd) spool in Dark Peach (solid, color code AC984).
At 12wt, Accent™ is a heavier thread than standard 40wt or 50wt sewing thread, so your stitches sit up on the fabric with visible dimension, texture, and depth — ideal any time you want the thread itself to be part of the design. It runs on all types of sewing machines, including longarms.

What is 12wt thread used for?
12wt thread is a heavy decorative thread. Because it is thicker than everyday sewing thread, it creates bold, visible stitches with a pronounced sheen — perfect for quilting accents, thread painting, sashiko, decorative machine stitches, blanket stitching, and free-motion embroidery. Use it anywhere you want the stitching to show.
How does Accent™ compare to regular sewing thread?
Standard sewing and piecing thread is usually 40wt or 50wt: fine, smooth, and designed to disappear into a seam. Accent™ at 12wt is a heavier, thicker thread with a lustrous rayon sheen, so it is a poor choice for piecing seams but an excellent choice for surface decoration. Pair the heavier thread with a larger needle (90/14 or 100/16 topstitch) so it feeds smoothly.
Frequently asked questions
Can I use WonderFil Accent™ in my regular sewing machine?
Yes. Accent™ is designed for all types of sewing machines. Switch to a 90/14 or 100/16 topstitch needle — the larger eye reduces friction on the heavier thread — and test your stitch on a scrap first. If stitches pucker, loosen the top tension slightly.
What needle do I use with 12wt rayon thread on a longarm?
Use a size 18 longarm needle. The bigger eye and deeper groove handle the heavier 2-ply rayon without shredding.
How much thread is on one spool of Accent™?
Each spool holds 400 meters (437 yards). This listing includes one spool in Dark Peach (AC984).
Is this color solid or variegated?
This spool is solid: one consistent color from start to end of the spool.
