I use almost anything for piecing even the dreaded coats and clark. Sometimes for a project it doesn't matter. I do use a lot of Aurifil for piecing some things and that doesn't seem lintier to me. I can also FMQ with aurifil if I like the color. I do have Isacord mostly, some Glide and some Omni. I also sew with serger thread and sometimes quilt with it too. So far nothing bad has happened. I did get some Madiera because I liked the color but it kept breaking thread on quilting no matter what needle I used. I'm using it up on scrap quilts for piecing. It seems to do okay with that. It wasn't old and seemed fine on the spool and with the break test. My sewing room gets very dusty. I think the combination of fabric, thread and batting contributes because none of the other rooms get that dusty.
