I have been studying thread and I was looking at a 1094 yd spool of Guterman thread and I can't find the weight on it anywhere. It is polyester coated cotton I think. Also do you match the weight of the thread with the needle or the fabric you are sewing.

I don't know the weight of the thread but I think you match both the fabric and the needle size to the thread you're using.

I was wondering if you found out what the weight was for the Guterman polyester thread. I'm still looking on the websites to see if there is any information on the weight of the thread.

I just looked at 2 different spools of Guterman thread. They both said 100% polyester, but no weight. They feel like 50, and are heavier than the 60 wt. thread that is labeled. I'll be watching for the answer when you contact the company.

See if this answers your question.

According to the Rowley Company website, Gütermann 100% poly thread size is Tex 30.

According to Coats and Clark, the conversion formula for getting from Tex system to weight system is (109/TEX) * 10.

Therefore, Gütermann 100% poly thread is 36.33 wt.

I also was wondering - about that. I use it for machine piecing and general sewing. Since I didn't know the wt I don't use if for anything else.
