This site was mentioned recently on one of the numerous sewing discussion lists that I belong to -- and I wanted to share with all of you.
http://www.sewingmachine-sales.co.uk/sewing_machine_info/video/sewing-machine-feet.phpIt's a good resource if you have feet you've never used, feet you are considering buying, and feet you didn't know existed but now will want!
I've been looking at a lot of rtw catalogs and so many times what makes a garment special (besides a good custom fit) is some special touch or technique. Having a special foot to achieve some of the looks just makes it that much more fun to sew!
