While even the smallest alterations in a garment can make a big difference in how the garment looks on someone, I personally prefer to save my tailoring budget for projects that are a bit complicated (such as taking in a waist, hemming denim, or anything involving a gauzy fabric).
I’ve found that with a little (and I mean a very little) practice, it’s really easy to do a great hem on a pair of pants or a pencil skirt. Not only do I save money, but I can do it while I’m watching TV or a movie.
The best hem stitch tutorial I’ve found is by sewingwithlaura on Youtube. It’s easy to follow and creates a quality invisible hem (you can’t see it from the front side of the fabric). No more waiting to wear those fabulous linen pants you just picked up!
