I got the pattern (True Lover's Knot) from a book called "Celtic Quilts" by Beth Ann Williams. It was SO easy to do! This is only my second attempt at this so you know it's not terribly hard. The real trick is using a fusible bias tape maker made by Clover. You feed both a narrow fabric and a narrow fusible strip thru the tape maker and iron it as it is formed. Then you iron the tubing into the design, which I traced from the book. I used a sheet of parchment paper in between so the pattern was easy to see. Sewed it in place with monofilament. It was really fun!
