I'm going to try this as I use the large spools in cream and light grey, the colors I do most of my sewing with. I have a metal spool holder but it's heavy so I don't like to take it with me to classess or sew ins. Presently I have my big spool of thread in a small coffee can, snap on the cover for traveling. Tried using a glass jar but that makes a lot of noise and annoyed the other sewers. May in Jersey
