I am probably among a host of people who have shied away from this group of presser feet because I did not know how to use them properly. I have this edition of Threads in my library, but this is the first time that I noticed and understood the importance of wedding the proper foot to the type of fabric. I can see now why I had so much trouble. I am getting ready to work on an evening skirt and this should make the hemming so much easier and more professional looking.
