I agree, if serger thread melted garment makers wouldn't use it because we iron (most of us) seams as we go. Rayon has a higher chance of melting that poly does. Serger thread holds up well. I even used it to do free standing lace on my embroidery machine. I was making Easter baskets for a bunch of my grandkids and I didn't want to use the rayon because it cost more and I would be surprised if the baskets lasted much beyond that day. It worked out great and much to my surprise, my daughters kids still have theirs.
