Posting here because not sure where to ask.
What are some good resources for learning basic sewing?
I'd like to sew on some velcro backing and a few Ace Combat/Danganronpa patches onto my M-65 jacket, and I'd like to learn how to attach them on my own. I already have a set of needles and some olive drab thread, looks like I might need some pins too.
Where should I start? Should I try some stitches on a plain tee shirt to get the hang of it first?
