We're making ours. We bought a popup portable gazebo (see picture below), so it takes about 2 minutes to set up and is free-standing. We are replacing the fabric that came on it with an ivory silk charmeuse.
The gazebo cost us $50 on eBay. The 19 yards of silk were $81.79 from OnlineFabricStore.net. I'll have to post pictures when we are done.
