I sooooo understand. I just finished a quilt top from a kit that came complete with pattern - it's laying on a bed right now waiting for me to pin the sandwich - that had so many errors in the pattern! I truly wondered if anyone had actually MADE the quilt! I've had that happen twice now and it's no fun at all.
Batiks are so beautiful and so forgiving, I'm sure yours will be fine. Mine has no future home picked out yet and is not for such an occasion as yours so it will be okay - just ... frustrating!
