I am sorry. I should have been more specific. Bob and Mother Superior are the folks who bring us those wonderful threads at Superior Threads.

I heard that Caryl Fallert used nylon monofilament for years, and you don't hear of her quilts falling apart!

I suspect that hard wear and exposure to sunlight will kill either one.

I always use clear polyester now that it is available, but I suspect there is not as much difference as people suspect.

Who irons quilts much, anyway? Maybe while under construction while you are putting on the binding, then not much.

Either one is kind of a pain because you can't see the darn thread while you are quilting! That being said, I do use it in the bobbin when I am quilting over labels and I don't want railroad tracks over my beautiful label.

Yeah, I agree with considering Bob at Superior to be the guru! Interesting.

I have ironed my quilting done so far with Sew-Art Nylon and it is just fine as near as I can tell.

Thanks for that info. Bears getting more info, that's for sure.

I mispoke so erased to avoid misleading anyone - besides myself! :

I just went to Superior threads and their MonoPoly is polyester invisible thread. Hope I can find some. I may be able to find it online. JAN

Who are Bob the thread guy and Mother Superior? /thanks, Jan

I don't have an answer for you but if you contact Bob--the thread guy, I bet he could tell you! Or even Mother Superior.

Is monofilament nylon? Does it break down? How do you work with it? I was told to use a metallic needle. HELP, Jan

lwiniger, thanks for you reply! I used the poly to stitch in the ditch just to stabilize the quilt so I could do machine stippling. For the stippling I used the YLI Jeans variegated thread and Bottom line for the bobbin and it has worked out very well. I thought about using cotton to stitch in the ditch but didn't know if I should or could. Thanks for your help.

Tani, thanks for your reply. I did some reading and searching and found out the difference. Thanks again

mamer, why use invisible thread on such a rugged quilt? if you're stitching in the ditch a cotton would be hidden just as well and in my opinion, hold up better.

Nylon melts at a lower temperature than polyester, so it is dangerous to iron anything that is quilted with nylon thread. Bob Purcell at Superior Threads recommends using polyester. I think you can't go wrong with his recommendation.

Good luck.

Has anyone heard that these threads are deteriorating with age? I thought I had read that they're becoming brittle after only a few years, especially when exposed to sunlight. If that's the case, what a shame considering how popular they are!

I'm confused , which is probably a terminal state . I'm working on a denim and flannel quilt and I will be using invisible thread for stitch in the ditch. Do I use poly or nylon invisible thread? Harriet Hargrave suggest nylon only. I need some words of wisdom from all you pros out there.
Thanks, Judy
