What? What? "Put down the presser foot before turning the tension dial?" That needs to be the first sentence in every sewing machine manual and how-to on tension! Over the past 40 years I have wasted hundreds of dollars getting my machines repaired to fix the tension but have still had problems! This instruction must be so basic that nobody thinks to mention it, so they don't! Thanks, Threads, for finally solving my problem!

I love your website, by the way, it is a vast source of information!
