DIY Embellished Sweatshirt

I love spring weekends and the outdoors. It's always been a dilemma what to wear to stay within my style,  without overdressing. Recently, I spotted trendy embellished sweatshirts, first worn by supermodels and then adopted by public. As the prices skyrocket for these little closet treasures, I thought it shouldn't be too hard to do in my studio for a fraction of the cost.

You will need:
1. Short-sleeve sweatshirt (I bought mine here)
2. Sew-on rhinestones (similar here)
3. Sewing supplies (needle, matching thread, scissors)
4. Ruler and pencil
