Refreshing Thread Weight when Poly vs Cotton

 

Embroidery Polyester 40WT Thread...... vs ..... Cotton 50WT Thread

Hello Quilt Friends.....   A bit of re-learning for me today.

I rummaged --- or Estate Sale shopped at a quilter's closeout of all her stuff this AM.

Isacord Embroidery Thread, 5000M, 40W Polyester Thread.  abt $9.00

my cost.... $2.00

A smaller weight number indicates a heavier thread

ISACORD is a polyester continuous thread that has a comparable shine to a rayon embroidery thread. 

Polyester thread is nearly twice the strength of rayon thread

Can I use Isacord 40 for quilting?

Polyester embroidery thread

 This 40 wt. thread is very thin, making it an excellent choice for free motion quilting designs that require a lot of travel stitching. Isacord is also very strong and able to take the high speed and intensity of machine quilting and embroidery.

What weight thread is best for quilting?

50-weight

Quilt piecing

The gold standard for piecing quilt tops is a 50-weight cotton thread. A few excellent choices for piecing are Aurifil Mako 50 weight cotton thread and our exclusive Bluprint Pima Thread . Both threads are smooth and fine, while at the same time being strong and durable
