Here are some of the ways I personally like to use black iron gas pipe for custom clothing racks. Extra piping and embellishments can drive up this cost and translate as steam punk; which for me is just another reason to keep the design simple.
My first projects were a parquet table and a pallet platform bed. I did it all with extremely limited tools in my backyard of the time. I loved the result and have been doing this since, slowly getting better at this whole custom build wood work thing..
