Wrapping a custom path around a textblock

Hi
I have a canvas where i have bunch of Textblocks and images spread around the canvas.
I need to draw shapes such as circles, rects, squares etc around these txts and images. I am attaching a sample picture which contains a text = "Two" and an image on the LHS of it.
If you notice i have a square around the image
and a rounded rect wrapped around the text and image
and another decorative path wrapping the two of em.
I am thinking we need to use Path here but just not sure how to achieve this. I am wondering if you could give me some direction how to accomplish this. I will really appreciate your help.
Thanks
N
