fix skinny jeans (or any jeans) that are too big. a good thing to know if you lose weight but don't want to splurge on tons of new jeans! (Or if you want to change flair jeans to straight leg or skinny)
Good idea to extend sleeves that are too short. Transform socks into wrist warmers. This is a simple, but very clever idea. If you can crochet and or knit, then there are lots of pretty edgings that you could use on these.
