How to hang a flag on the wall?

I have several flags that I used to hang on a flagpole. We now live in a condo. I would like to hang a flag as wall art on a stucco wall on a balcony. We are not allowed to put holes in the stucco wall. I tried hanging one with a dowel rod and string and hanging it across two command hooks attached to wall. However, wind blew it down. Any ideas? Thanks.
