This is my solution and works:
CSS:
.box {
border: 5px solid lightblue;
border-top-left-radius: 20px;
border-bottom-right-radius: 40px;
}
h2 {
background-image: url(star.png),url(star.png);
background-repeat: no-repeat, repeat-y;
background-position: left, right;
text-align:center;
padding-left:30px;
padding-right: 30px;
}
