Polyester Thread
 

I'm not sure how, but I have ended up with quite a few spools of 100% Polyester thread, several which are Guttermann. Can't see a wt. on them. What can I use this thread for?

Great for Quilting.

I use it for all my quilting from piecing to hand quilting. Never have need for anything else except Invisifil for hand applique.

The other day I found a spool of Coats and Clark poly that I've had a long time. I don't buy that brand anymore but it's working out just fine for piecing. I used it in both the top and bobbin. I intend to use it up. My Bernina isn't fussy about thread.

Why would the thread being poly worry you about using it? If it's thin use it for piecing. Guttermann is a good brand of thread.

I use polyester thread all the time for piecing and have never had any problems. I even use serger polyester thread for piecing. I only use cotton thread for quilting.

I love using serger poly thread for piecing and I've quilted with it too. My machine isn't picky about thread at all, and I find the serger poly to be even stronger than the 50wt Aurifil that I splurged on. Use it up with no guilt :)

I have lots of older thread and I just use it. Mostly for piecing, can't tell the difference.

I almost always use a cotton/poly blend for piecing and often a poly for quilting on the LA---and I much prefer Coat's cotton/poly blend for hand stitching the binding down. it's strong, isn't linty and works great in all my machines.
