We all have old sweaters in our closets that don't get much use, so we were on a mission to find a way to repurpose those pieces and make them stylish and new again. We decided to give our knit a little flair with an embellished collar made out of studs and rhinestones. It's really easy, and a simple way to transform something you already own — plus, it feels entirely festive for the holiday season. Watch on to see how it's done!
