I really adore the idea of sewing. What a shame it is that so many people have no idea how to do it, and I'm not just talking about women and gay men. At the very least everybody should be taught how to hem and sew a button on. Don't you think? A button? Is is really that hard?
I know that both hubby and Sir Braveheart could do both. How about those in your family. Can they sew simple things or do they rely on you? Sir Braveheart would probably be better at sewing skin rather than fabric, but hey knowing how to stitch is knowing how to stitch.
So in response to Peter's hammer and nail analogy. True! Building a house (and I know from hubby's experience what that takes) and building a bookcase are a horse of a different color. I am still at the bookcase stage while Peter most certainly is at the two-car garage with electricity and plumbing stage. Just like anything else, unless you are a savant of some kind, learning to sew takes patience, practice and learning new skills.
The answer to whether or not it is easy would depend on my mood or my proficiency at the time with whatever garment I might be working on.
Easy? Relatively. It's not rocket science.
Easy? Hell no. I screw up all the time.
