What thread to use?
I'm getting ready to practice a on a small sample of my first quilt. My fabric is 100% cotton and will be using warm and white for the batting. I need help in trying to figure out what weight of thread to use for my machine quilting. I used 50wt Aurifil thread in 100% cotton for my piecing but I'm not sure if I should use a 40wt or the 50wt that I already have. Is there a better weight for strength or are all machine quilting threads equally strong? I have already purchased a cone of Coats and Clark in a 30wt from Joanns, but now I'm second guessing my choice. I read that the heavier the thread, the more your stitches will show. This is my first quilt ever, so I really don't want my mistakes to show. I have a Singer Confidence 7469Q sewing machine and don't know if I would need to adjust my tension for switching to a heavier thread. Also what stitch length should I use? I will probably do straight stitch quilting. Any help out there would be great. Thanks!
