I mostly use Isacord Poly for machine embroidery, but I met a lady at the quilt shop who uses for piecing also. I usually piece and quilt with Gutermann poly, so I suppose it wouldn't be a lot different.

I rarely do the type of dense quilting that Leah Day does, but I know she uses Isacord to free motion quilt.

If you have a serger, it is very good for decorative edges and flatlock embroidery.

You can roll up a ball of the htread and do a burn test.
•Polyester: Has a somewhat sweet chemical odor. The residue is initially a hard cream-colored bead that becomes darker. Flames gives off black smoke.
•Cotton: Burns, but does not melt. It has the odor of burning paper,
•leaves, or wood. The residue is a fine, feathery, gray ash.
•Hemp: Same as cotton
•Linen: Same as cotton
•Ramie : Same as cotton
•Rayon : Same as cotton
•Silk: Burns, but does not melt. It shrinks from the flame. It has the odor of charred meat. The residue is a black, hollow irregular bead that can be easily to a gritty black powder. It is self-extinguishing, i.e., it burns itself out.
•Wool, and other Protein Fibers: Burns, but does not melt. It shrinks from the flame. It has a strong odor of burning hair. The residue is a black, hollow irregular bead that can be easily crushed into a gritty black powder. It is self-extinguishing, i.e., it burns itself out.


I remember doing burn test on fibers when I was in school for Marketing many many years ago.

I use my little bits left on the spools for top stitching.

You can use it for quilting or for thread painting. Oh detail on applique too. Its good strong thread, so just use it.

i intentionally buy embroidery thread for machine applique...i also use it for FMQ.......

I also use it for machine quilting.

Good for hand applique with all the colors available it is easier to match the fabrics and hides well.

I use the verigated threads for machine quilting, especially for kids scrappy quilts I make-not that I actually quilt very much, but when I do....
