Always nice to share a reputable business - The Colorfulworld of Sewing. Whether you are looking for sewing machine feet, serger feet, or sewing accessories you can certainly find it here AND personal customer care. I needed some feet very quickly for my serger, and they arrived in no time. These are probably 3 of my favorite feet - gathering foot, piping foot, and the beading foot.
If you haven't used your serger for a while, time to pull it out and see what feet you may have. They make so many tasks easier!
