Knitpicks had a one year exclusive on the pattern but the rights just reverted back to me. I've gotten quite a few questions on exactly how the butterfly lace is done, so I updated the pattern with a step-by-step photo tutorial and released the updated version on Ravelry, Craftsy and soon Love Knitting (for European buyers who have to pay VAT.) It's actually very easy once you figure out what the text means. I guess the test knitter was very good, absolutely no questions. Maybe designers should look for "average" test knitters so the questions would come before the pattern releases.
