Hi. I'm working on a duster coat and I'm using this cansas material though its pretty finely woven unlike duck canvas. unfortunatley, I dont have any idea how to choose thread properly. It doesn't help that there are like a million systems for thread size and a lot of thread isn't dierctly labeled. I plan on doing flat felled seams because i want it to be durable but I don't know what size thread to use or really what size my machine can handle. Any help?
