I too have a Pfaff 2144/70 with the IDT. My earliest Pfaff 7550 also had the IDT (built in walking foot) BTW it may not be a presser foot-but the needle threader is invaluable~

I find my two favorite feet are the 1/4" foot that I use for piecing quilts and the stitch in the ditch foot--also for quilts. BUT This 1/4" foot helps sew nice narrow seams for collars, etc, and for top stitching. the SID foot makes waistbands and collars and other types of techiniques neat and professional. When I have a facing on a blouse, I stich it down at the shoulder seams using stitch in the ditch, invisible but secure.

I love the cover photo! Here in Jordan the American Women had a Crazy hat luncheon, wish they could have seen the ideas here. Maybe next year!

Thanks for the clear instructions, close up on how to achieve this professional detail. However, to qualify that the stitches go from right to left--that is if you are a right handed sewer. We lefties will go from left to right!

This is one of the best articles about sewing sheer and silk fabrics. I came looking because I want to make a silk chiffon skirt--and the fabric was very costly! So can't afford any errors. I think the double zig zag will work perfectly. thanks again.
