I just found this link from Voodoo Rabbit blog, with some simple and great little tips on how to hem your clothing. Check it out if you want some new ideas on how to finish the edges. Unless, like me, you just keep them raw because you're too lazy to bother finishing up that last little bit to make your new skirt or dress look perfect! (seems I'm not the only one, so that's okay).
My favourite is a faced hem, but with a really big facing, which means you have the hem stitch line about 5+cm above the hemline. I like the look of it, as it's a bit different to the regular 1/2cm (or less) of most seams. Bit designery, no? That's how I finished this skirt hem.
