We were looking at it when I picked it up and she spotted a little spot, but acted like it was no big deal so ... I did the same. I looked it over more closely when I got home. The more bothersome spot had a place with an extra long stitch - as if the needle had skipped a spot, then there was a bit of good stitching, then the place where there were holes, but no thread. Sounds like timing to me in my totally ignorant opinion!
