I know there are good youtube videos for making piping and applying to pillows because I used them when I made throw pillows a few years ago. I don't have the exact one I used saved to this laptop, sorry. If you just go to YouTube.com and then do a search for making pillows with piping you will easily find many helpful videos. Just keep looking through them until you find the one that works for you. I know that mine did not require a special ruler for the bias piping since I don't have one. I do remember getting the "string" or cording for the piping at Joann's. Good luck, I thought it was fun to do.
