The umbrella is free standing, which I love – we can move it around according to our needs.And we put it away into the garage for the winter.But it’s quite heavy and when open tends to flip.The temporary solution we came up with was the sand filled bags. They seem to do the job, but are not very sightly or esthetically pleasing. Any suggestions to remedy this?
