I took a $1.50 bunny hand towel from Daiso and put it on my old navy pullover!
If you want to try, I fray checked around the edge of the bunny and cut the bunny out. I pinned the bunny carefully onto the sweatshirt making sure not to catch the other side or the pocket. I then basted the bunny on and used a satin stitch to applique it on. Ta da!
