I bought the hammock in the picture above years ago while traveling in Brazil. I went to the factory where they were made and watched as the men wove the body of the hammock on huge wooden looms. The women sat on the floor and crocheted the valences. This hammock has moved with me from home to home. Most of the time I have hung it inside filled with pillows. It's my favorite place to take a nap.
I recently ran across an article in Apartment Therapy that is about hammocks and swinging chairs used indoors. It has some great ideas.
