#1 is a quilde for quilting straight lines once you get your first line straight. #2 is a 1/4" guide. I have one on my piecing machine. #3? 4? #5 is an early upper feeder - yes, an early walking foot. # 6 and #7 are for zippers or cording. These are short shank attachments and will fit a lot of modern machine. My fav is a ruffler. It looks like a minature instrument for torture.
