Gutermann thread
I acquired several spools of Gutermann's Tera 420 threads at a garage sale. Beautiful,fine thread. Thought I would look it up online to learn about its fiber content, properties, etc. Can find almost nothing. A couple of links suggested it was for sewing ripstop fabrics. It doesn't seem that this is it would be appropriate but I was interested it using it for general sewing,quilting. Any insight and info you would have about this trhead would be great. Thanks!
