This is what is used to make turbo blankets and anything else that is fire resistant.

Kevlar thread it a tex 90 weight thread with a 17 lb breaking test that resists temperatures up to 930 degrees. Designed for use in sewing fire-resistant fabrics and geotextiles. Unaffected by most acids and alkalines. Mildew proof and excellent resistance to aging. ULC approved.

I could only buy a massive spool of it, but have the means of putting it in ~100-150 yard bobbins for personal use.

Thinking around 10 bucks shipped per bobbin of thread, most of the cost is the bobbin and shipping.

 

How much do you have, and how much for all of it.

 

I have about 4500 yards (a 1lb spool)
How does $200 sound for all of it???
