oh yes...they were industrial and very HOT to have in the 80's during the "country" decor rage... it should be a steal at that price! BUT how many ruffles are you going to make in your life time...those machines were designed to make those lovely country ruffled curtains..MILES of ruffles...nowadays they are used to mainly make costumes/ ballet outfits, anything with multiple layers of netting/tulle to make the POOF factor explode!
