this was a fun project for a friend who needed new cushion covers for her kitchen chairs. she chose the fabric - a lovely coated cotton with an abstract chrysanthemum pattern. there were a ton of videos on youtube to help learn about cutting bias strips for piping and sewing it onto cushions. i bought sash cord from the hardware store - 45 feet for about $2 - much cheaper than the fabric store. now i'm looking around the house to see how i can incorporate more piping.
