Use whatever stitch you want on the project you're doing. I've used straight, zig zag, blanket and satin (usually a stabilizer is needed with the satin to keep the stretching to a minimum). I've also, on occasion, used more decorative stitches. There's no wrong or right, just preference. If your machine has a Needle Down option, now is the time to use it. Go slowly, be aware of where your next stitch is going and just go for it. I usually do some practicing on a scrap first, get my settings just where I need them then mark right on my machine what they are. I use a fine point Sharpie. That way the markings are there when I need them. When the project is done I simply use an alcohol swab to remove the Sharpie marks. If I'm working on several projects at a time I use different colored Sharpies.
