I rarely machine quilt, unless I am learning a new technique. I usually use Coat's and Clark Dual Duty then. Don't know it is best, I just have it and it is usually on a wall hanging, or something that does not get hard wear. So, I am not an expert on what is best. I am afraid I can't help you there. I did not look at the organic, closely enough to see if it was Egytian cotton or not. I just noticed it, never had seen it before. It was over $6 a spool. Sorry I can't help. For what it is worth, I know some quilters who say they cannot use Coats and Clark in their machines, that may be as important as anything.
