Signature 40wt thread is the best to use for quilting.

Blended great with my backing used. Signature thread never fails me. It is the only thread brand I use on my long arm machine

Good color, good thread

My previous supplier of Signature threads seems to be phasing it out. I am so happy to have found Red Rock Threads. They have a great selection and they shipped promptly.

I love Signature Thread. I’ve used it for years with my long arm.
