Another machine foot attachment I inherited from my mother-in-law Barb is the 1/4 seam foot. Many quilters or patchworkers will have one of these attachments in their sewing drawers as most patterns call for a 1/4 seam. This attachment is for a basic Janome model.
As I work towards finishing my daughters quilt, this attachment with a 1/4 inch metal edge guide has made piecing the quilt together a breeze.
Your fabric pieces rest up against the metal plate giving you a perfect 1/4 inch seam every time. Making it easy to match up corners and seams
It also reduced seam bulk on the reverse side of your work.
This sewing machine attachment would also come in handy when you can't see the markings on your sewing machines metal needle plate.
