"Use what you have!" That's the motto when it comes to creating a new style to a rather plain garment. If you have a plain sweatshirt or if you need to buy one head to Walmart, and style up a bland look. You can use any color sweatshirt you'd like, gray, teal, red, royal blue, pink, it's up to you. All you'll need is rhinestones (try Michael's $2.49). You can even use old post earrings by taking the pointed part off, plus have a glue gun handy or fabric glue. If you want to add some cool designs you'll need fabric paint, paper, pencil and scissors.
Be creative and make sure to show off and share the final results. Here's to being able to DIY!
