Arrrgh! I don't believe it!

In spite of us all coming down with some flu type thing, I was feeling pretty good about how the testers were going. I was just about to get some finished while the little one has a nap when I realised I have put the snaps on the wrong place ON EVERY SINGLE TESTER!!! I can't believe it, the instructions I've made even SAY where to put them WITH A DIAGRAM and it isn't as if I haven't done it before. I obviously just got into a rhythm and did them all that way. The sensible thing would be to keep them as seconds and start again, but this is my last fabric until the rest arrives from Canada!
I think I can fix it but I don't know what it will look like. If I drill them out it might look sloppy, but if I leave them there it could be confusing and obvious there is a mistake. Of course I really wanted the testers to be perfect - I mean this is what I am offering to sell. It is purely aesthetic, it can't affect the function of the nappy, and it will be covered up so not even visible when it is on, but you know what I mean.
Sighhh, fingers crossed this works.
