"Polyester will melt from a hot iron"

I didn't find that it did when I made many string blocks using up old half empty spools of poly thread. I did press the strips with a hot iron as I added them onto the backing, and also pressed the backing where the thread showed and never had anything melt. I've also noted that many long arm quilters use poly thread.

I usually use Connecting Threads thread in neutral colors for piecing, love the light gray as it goes with everything.

Aurofil all the way. For piecing it is great; being only 2 ply I finally get the size of quilt square that I need; before it was always too small. Very little lint. For quilting it also works great; Viking recommends it for my Viking mega quilter. It comes in alot of different colors including varigated.

The Superior Threads website has a fantastic section on thread usage.

Right now I also use pretty much all Connecting Threads thread. You just can't beat the price and selection. It does lint up A LOT when machine quilting though. I use a light/medium gray for pretty much all of my piecing.

I don't really care if it is cotton, poly, nylon, or rayon. If I like it and it works on my machine I'll use it. I have a lot of Aurifil and Connecting Threads Essentials I'm using now. Both brands have cotton and poly threads, doesn't matter to me when I'm piecing. I use the prettier color thread for machine quilting or decorative stitches. Any good thread will last in a quilt much longer then I'll be alive so why stress over it?

I use the cone thread from Maxilock.
