Before husband John braced it, it swayed. And it didn't look like a flag waving, but rather just a slanted flag. Now it is firmly in place and painted and ready to set out on a porch or patio or even inside in a great room or entry if that is your style.
I really try to use what I have and put it together in a new way so it conveys the feel of the holiday. Can be as simple as a flag in a blue pot or planting red, white, and blue flowers such as red geraniums, blue lobelia, and white petunias in a galvanized tote.
The important thing is that it reflects your personality while decorating for the occasion.
