With so many seams, being off just a couple of threads adds up to a big difference. Marking on you machine bed isn't difficult or expensive and a 1/4 inch foot is a great accessory. IMHO

While I don't have a ¼" foot, my machine is marked at that spot and there is also a kind of divider on the foot itself. I've used both as guides. I would never claim to sew perfect seaming, but I don't think they are terribly far off. However, as you say if each seam is off by a couple of threads... One of my accessories is a "cloth guide" which you can put in several places to guide your seams to supposed perfection. I tried it for about an hour and found it to be not only often in the way but also not necessarily more accurate than using the marks already on my machine.

OK, just to be sure, I got out my 6" ruler and checked seams on a couple of blocks. They are ¼"and yet the blocks are not perfectly square. I can only assume they are all ¼". Something else is causing the slight skew.
