Making piping is a simple process. Simply take your desired piece of fabric, and cut a strip 3-5″ wide. Fold the strip over the cording.
Sew the cording into the fabric. The goal is to get the needle as close a possible to the cording, without sewing over it. Take it slowly. I usually break a needle or two (or 10) when I make piping.
Notes
I think piping can really finish off a DIY project and make it not-so-DIY looking!
