I really like bagging a jacket or coat. There's something wonderful about turning it right side out and it all being nice and neat. I can imagine and rotate 3 D objects in my head so it feels fairly obvious what goes where to me anyway. Plus I'm not great at handstitching.
Having said that I'm just unpicking the lining on my latest make because its slightly too short at the sides/back, but ok in the centre front, and I probably wouldn't have to do that if I had hand sewed it!
