My first OBW, I bought some beautiful In The Beginning fabric. I was taking a class so did not wash it as instructed. During the class, my instructor noticed I was having trouble matching my fabric strips. After checking, we found that the last (maybe first) part of the fabric has been printed askew on that part. I lost about a foot of fabric as that was unusable! So it can happen with a new, quality piece of fabric. I was able to make my OBW but it wasn't as large as I'd hoped.
