I use a lot of YLI Invisible thread to machine quilt. When I finish each quilt, I use one of those masking tape lint rollers & roll it across the rug. That Invisible thread is really bad for vacumns. When I 1st started to quilt, I taught quilting in a sew & vac shop & when servicing my machine, he showed me the melted thread whre the brush roller attached to the vacumn.
