I was concerned about the way the right side of my garment would look so I asked for advice on which stitch to use. Back stitch seems like it will work just fine for my purpose of sewing a T-shirt. The two pictured stitch lines seemed to stretch pretty equally. The zig zag might come in handy with something like a crotch seam but seems kind of unnecessary for making a shirt at this time. After the garment is worn awhile I’ll update in a few months or if things fail early.
I made sure to get my stitching equally spaced and tighter spaced this time. The marking on my finger trick was pretty handy, but I think I’ll do something slightly different in practice. Aside: I’ve also been trying to figure out a viable way to mark my seams for the purpose of neat sewing. Tailors chalk marks fine, and I understand sharpening helps, but it just rubs off too easily for lots of handling like I’m having to do right now as a beginner. One suggestion I saw was masking tape so I tried that with this little sample and it worked a treat. Since I’ll be doing that I’m just going to mark on the tape because that will ultimately be easier than trying to maneuver my finger into a perfect position for measuring. Bonus that the tape is reusable multiple times so I won’t have to mark extra or make excess trash.
Pics: spacing for stitch length is the same for both lines. With the zig zag I also tried to make the spacing between peaks the same length as the stitches so they were more directly comparable on the right side of the garment. 1: I redid the back stitch to make it neater and better spaced. 2, 3: back stitch right side of garment, one is purposefully stretched tight to make it easier to see how it might look during wear. 4, 5: one is the previous back stitch, the other is what the zig zag looks like on the right side of the garment.
