Did you hear the story of the young woman making a ham and as she put it in the pan she cut the ends off? When asked why she looked at her mother, who then looked at her mother, who then said "Because my mother did and this is the only reason." We do what we learn and we enjoy it cause it gives us pleasure and it works. I have only used cotton quilting thread....why?....Because my quilting teacher told me to! It works, it gives me pleasure so I have been happy enough to go along my merry way. I have learned so much on this site but honestly when I think trying to use it all sometimes my brain just hurts. Thank for the info in your post and the lively discussion that followed, always a good thing. As long as it works and it gives you pleasure, that is all that matters.
