In case any of y'all are familiar enough with sewing foo, here's a question I just put up on /r/sewhelp:
I'm only just starting to teach myself to sew with knit fabric. I don't have a serger, just a Singer 4411 and a couple of different presser feet. One of them's an overlocker foot, and I've watched several videos on how to use it, so I think I have a general idea there... right now, though, I'm trying to figure out something slightly different.
I'm very close to finishing up an attempt at a T-shirt. I've sewn it out of ITY fabric, mostly because the fabric was on sale for dirt cheap and I figured it was a good way to practice with knits before moving on to proper cotton jersey. I've been using zigzag stitch and polyester thread and I tried stretch interfacing on the shoulder seams, but wound up ripping them out and redoing them with strips of reinforcing cotton from a different t-shirt instead. That part's fine so far. I tried the shirt on last night and I seem to have done okay fit-wise (it was a cloning attempt using an existing fitted T-shirt as the source). Before I hem the bottom and the sleeves, do I need to do any finishing on the internal existing seams? I know they say it isn't as important on knit garments because knits don't unravel, but when I look at the interior of other T-shirts I have, they appear to have had the seams finished with whatever industrial serger they had at the factory. Do I need to do seam finishing on this thing? Or on the eventual cotton jersey shirt I plan to make now that I've demonstrated that the drafted pattern is viable and fits me properly?
