I swear I found some online instructions for this, and they're bookmarked on another computer. Nothing on youtube, though. If I find it, I'll post it. I also have started altering my clothes with a sewing machine - mostly slimming/hemming pants, but also slimming a couple of t-shirts. I figured out how to do the whatchacallit - flat lap hem, like on the inner seam of jeans - but it is time consuming and a bit more difficult to keep straight. As soon as I finish my master's thesis, I'm going to start buying shirt patterns and making my own from scratch!
