Blind Hem Foot

Yesterday I used the Blind Hem Foot on my sewing machine. Really cool. I have always had lots of feet that came with the machine and never took the time to learn to use them. What is the purpose of having them if you can not use them? I was hemming dress pants for a customer and decided to try it. Really Really Cool. It takes a little bit to figure out the way to fold the pants but less time than to sew them by hand.  Try a new foot and tell me about it...
