All the time :cry: And it's very hard on me too because I have the mindset of a perfectionist, but the ability - not so much! I never cut right, I never stitch right - always just a little bit off. So I am really taking note of all the suggestions here. And to make matters worse, I just discovered that my quarter inch feet ( I have two) sew slightly different quarter inch seams :thumbdown: So just like different brands of rulers being differently marked, so are the quarter inch feet! Come on people, help us poor quilters out here. Sewing machine makers give us more light and a wider throat on the machines, foot makers make your feet accurate, ruler makers, ditto!
