Trying to work on my Katamari Cousin tonight... previously, I had done an awesome job (for me) of sewing an invisible zipper into the back of the costume - everything lined up perfectly. Except that the fabric had stretched a tiny bit while I was sewing and the zipper sat lumpy when I wore it. Since the neck had also ended up too tall, I decided to rip out the zipper, shorten the neck, and replace it. Everything worked out fine - my zipper isn't lumpy anymore! EXCEPT - my neck seam doesn't line up anymore T_T It's off by a full 1/4"
Think it's worth trying to rip out again and trying to get it to line up? (yes, I am aiming for masq-level)
