Every time I've purchased a walking foot, and yes I've purchased a few, the first thing I do is throw the guide arm into one of my sewing boxes to gather dust.
A little while ago I shared with you how I was making a quilt for my daughter. I'm quilting each square as I go and could of really done with one of those guide arms that I had carelessly discarded.
Well, while I was searching through my things for something else I found one. I was soooo excited. As a result I have been motoring through the squares and they are almost ready to piece together.
In case you haven't used an arm before, here's what you do.
The guide arm is a separate metal attachment. This is a walking foot for a Jamone so other machine attachments may vary.
Firmly push arm into place and slide out to the measurement you require.
The guide arm should rest on the stitching line, fabric edge or seam that you are wanting to use as your guide. Then sew, the guide will glide over your fabric.
Say goodbye to wonky lines.
