I have two - one in my sewing room - covers the double doors that go outside (that I don't use, they stay locked 24/7) - I used a tension curtain rod - just slid a flannel top sheet onto it - ta-dah! My other one is for retreats - my best quilting buddy made it for me for my birthday - pvc piping for the frame - stretch a flannel fitted sheet around it - ta-dah! I love them all, including my buddy!!
