Sorry for the lengthy time it has taken to reply to everyone regarding my problem with the border twist on the Attic Window Twist pattern but I have discovered my error. Somehow, my 1/4" seam allowance was out just a fraction but sufficient to put the darn thing out. With the unpicking, the fabric frayed and so will have to purchase more fabric from 1000 bolts.com and attempt it again but this time, it will be completed with a great deal more caution. Thank you very much ladies for your assistance and suggestions - so appreciated.
